Done a quick calculation on ROI and   

Many thanks will look more at A2 then

In your case with being away from miner, I would go for the A2-30.  With it being all in one I think it fits your needs of remotely being operated very well with it's consistency, and being a all in one unit.  It just took a pretty good price drop at the moment for you I would give it a look.  Also is most energy efficient chip aswell.

SF-28 is still a good unit, but with you being remote I think you will enjoy the A2-30 for your situation.

My T1 Dragon is down again. eems like it is hashing half days only. I am very disappointed, this is not I was expecting. Any idea how to improve this? WHen my Dragon is going to be back on-line? Are we going to see this repeatedly? What is the reason of this? Is your data centre a stable place?

so you want to run the unit in house.   so to speak.

I have gridseed blades 8 of them hash at 40mh pull around 700 watts.

 pluses   
 cheap you can get a 4 pack for 1700   so 16 = 6800  usd for  80=82mh
   
downside 

16 need about 1400-1500 watts of power  they also need to be maintained .  they are not like s-1's  which are set it and forget and will start back up after a power failure.

the top of the line unit right now  is sold by lee on this thread.

the a2-86mh miner for 9199

plus side it uses 850 to 900 watts vs  1400 to 1500 watts for the gridseeds 

  so you save close to 12 kwatts of power a day  .  look at it this way 12 k-watts is 2 dollars maybe more or less.

price for the 16 gridseeds = 6800usd  price for the a2-86m = 9200    power saved 60 dollars a month  that means 40 months to make up for the power.

So buying the top of the line miner for 9200 is pretty dumb if you think power saved is the only thing that matters

 Now there is more to figure ..

 the top of the  miner has 3 or 4 wires max

  16 gridseed blades has about 68 wires
 the gridseed blades will sell on ebay one at a time pretty easy.
the  16 gridseed blades can be point to 32 different pools  since each has 2 usb connections.
the gridseed blades can use a 92 mm noctua fan and be very quiet.


 You need to weigh what you want to do.
 Maybe your uncles place has great power prices 6 cents or 8 cents
 Can your uncle check on the gear?
 The A2-86m can run remote.
 The gridseed blades are a bit more simple  and I don't know how to reset them remotely.

It is a tough call  if the a2-86m was about 7599  it would be go get it. 

but at 9200  it does not compete well against a guy like me that has the much lower cost gridseed blades.

remember on one level both you and I are looking for the same coins.

So if you get the 9200 dollar piece and I get the 6800 dollar piece and can do the work needed to run them I am better then you.

Look at it business wise.  I am retired = time on my hands.  I have worked with computers for about 40 years.
 I go back to the big old ibm mainframes.

I can do    16 of these gridseed blades.     so   that is  about 6800 usd  and about 82mh 

so I am 2400 ahead of you  .  take away 2 psu's for 350 some extra hubs.

 I am 2000 usd ahead of you with about the same  hash.   my power is 2 dollars a day difference.

Since my labor is 'free'   It take 1000 days for you to catch up to me.

This is why right now I buy gridseed blades. Not the A2-86m

Many thanks for detailed response

I have some Ants which are open case design and they are working without issues for 7 months That's why I was looking at Silverfish miner but than I read that they are not hashing reliably. I have my miners at my uncle which is 2500km away so unless they work 100% of time like Ants I can't afford to get them because he is unable to fix them.

Size doesn't mutter to me, I have 5x5m room available to use and so far I have only couple of Ants and habaneros there.

Which one would you get ?
(there are just couple reviews on BtcTalk)

On the Lee Group guide for the SF-28 in the second post it show the best to do if you have a unit not hashing up to speed https://bitcointalksearch.org/topic/m.7285593 .  It has been noticed not all blades hash the same as mentioned before.  The SilverFish is a good unit with great expandability, and they have focused on a lot of features it seem for miners.  The SilverFish program is it's biggest strength being able to switch pools in a matter of seconds on up to 100 miners, monitor all miners very easily, install additional unit within minutes, etc.

There has been a big adjustment on Scrypt miner prices.  The A2-30 is much less susceptible to heat being a closed air unit, but it also is larger in size.  But it's all enclosed with no computer needed.  Depending on your conditions and what you are looking for is what I would judge which miner is better for you.

I purchased my machine and I own it, lee hosts it.

 I purchased when coins were 450  with coins now  at 600 I will make a cash profit.

Untrue.  I should pay my miners off in 3 months unless the btc really drops.

Are you guys really renting terahashes? Isn't it the way to never meet ROI if the btc price won't skyrocket?

Did you sort out issues with SilverFish miners guys reported couple of pages back ?

Thank you

i have restart your miner and what is the hash rate now

my one miner in the professional center just ran perfectly for 29 days in a row at 1.022 th average.   

it stopped this morning and i reset it via remote access. I am tempted to get one more.

Mine are in the professional data center also.

both of my miners are in the professional hosting centre and both are running at just over 1 th/s right now on ghash stats.
sometimes they drop down to 950 but i think that is ghash stats reporting as if I check them via remote access they are going at over 1 th/s.

Did you guys check your hashrate to make sure it is 1TH/s .  All my miners are in the 700s.  I think the data center is too hot.

Ok, I have a question here about the host fees..
On all the documentation posted and received so far it has been a monthly charge of $225 up until the 21st then $185 from the 21st.
On the last bill that comes it is a daily charge of $7.5 a day which = $232.50 on a 31 day month and $225 on a 30 day month.
So for last month we get a bill for $232.50 per miner instead of $225 ?

After the 21st what will the $185 part be, a 30 day charge or a 31 day charge ?
$185 for 30 days or $185 for 31 days ?

So which one is it, a daily charge or a monthly charge for the host fee billed monthly ?

Absolutely the correct thing to do in my opinion. Thanks to Pcfli for clearing it up so quick.  I was wondering the same thing.

yes that is why I checked to see if I was paying the correct person.
