Don't forget that there are EBay fees, Paypal fees, shipping costs, fees to turn that fiat back into BTC.  I've had zero feedback bidders not pay, resulting in more listings, and the fees just keep starting over.   Overall it's a really inefficient way to move these units.

Granted there are Ebay and Paypal fees, but shipping costs should be paid for buy the buyer, and the BTC buying fee should be pretty minimal if you use the right source.  Also, a non-paying bidder just means a waste of time, as there would be no fees involved when ebay refunds the final value.

Overall though you will only see any profit in these units if you buy them in one of the group buys and sell them on ebay in the next few weeks.  Let's do the math.  Using https://bitclockers.com/calc, at current difficulty, 1200 Mh/s will return .0539 BTC per day.  1 unit can do 300 Mh/s, which would equate to 0.013475 BTC/day from a single miner.  The group buys are going for about 2.15BTC.

The breakeven point, assuming no difficulty change and no electricity cost is 159.5 days

Factor in difficulty increases and forget it.  In 3 months the difficulty will be so high these will be generating next to nothing.

Most recent one on eBay sold for $485 (3.7 btc) but obviously demand will drop as more are offered.

I don't think that could ever finally make some profit.

Buying these on ebay is a bad investment. I expect the chance of getting a ROI would be slight, I'd guess at maybe 10%.

Buying them new, for 2.1 - 2.8 is arguably a good investment. I personally don't think they are, but I think the majority believes they are.

The best ROI with these items is in fact purchasing them from the source, and then reselling them, on ebay or your own store.

The product is sexy and has a lot of merits (power,heat, ease of use) but I believe at this juncture, when we sort of between 1st and 2nd gen asics, and difficulty rates with big-papa asics coming online, that there are better investments to be made.

One exception would be perhaps for folks that have live in areas with much higher energy costs than most.

To me, it is clearly way too expensive!

If you look at the price of 2 avalon chips, it will cost you around 0.18 BTC for the chips...

Even if they don't have a good PCB assembly, they win at least 1.2-1.5 BTC per Unit.

But in the end, everybody would do the same: the demand is skyrocket high and they are the only ones shipping.

What the ASIC is going to do is enrich people that had already a lot of bitcoins and were the first to order and receive ASIC. Manufacturers and resellers will also get rich.

All the other ones will pay very expensive rigs and will barely have an ROI.

To me the best thing to do is buy bitcoins through a trading platform and keep them for two months or so.

End of Aug, people will start to realize that unlessnthey spend a lot of money buying expensive ASIC material, they won't profit anymore and start selling their bitcoins. And then... I'm quite sure the BTC exhange rates will drastically go down.

meh they don't look worth it for the price.  might as well wait for a BFL order then buy two of these....

BFL is still vaporware for now, these may not be worth the price but at least they exist

so when is someone going to post the howto make these miners..

http://www.em.avnet.com/en-us/design/drc/Pages/Xilinx-Spartan-6-FPGA-LX9-MicroBoard.aspx

looks to be the same..

can these be used?

I'm working on blog post, for something about the same cost @200MH/s, but my shipment of boards is stuck..........

Because I don't have any Bitcoins yet. :p I'm not in a position to buy Bitcoins at the moment. I've only got about 0.01 BTC.

I really don't think more than US$1.00 / Mh/s makes any sense. Basically, you're deciding whether the power savings significantly reduces your cost vs a GPU. Also you are weighing how long it may take you to break even.

This being said, i'm bidding well above this on ebay(and losing) just because i want one in hand. yeah, i'm stoopid.

Why are you not in a group buy for this, then?

There is a big difference between LX9 and LX150 (that does about 190-200 MH/s BTW).
And you cannot power LX150 from a USB.

IMO worth about BTC0.2 as you can buy the chips for BTC0.08-0.09 each for assembly on a K16 board

Probably 2 weeks from the moment someone gets the bright idea to spend next couple of weeks writing code for a device to mine (probably) less than 5 MH/s @ $89

IMHO the 5 MH/s and 2 weeks is me being optimistic.

Edit: Corrected typo. the usb thing is $89 not $8

They are probably worth 1 to 1.5 coins. Overpriced in my opinion but plenty of people are buying them so they are worth what they are selling for. I personally don't think they will make back their investment though. Although they might if Avalon and BFL continue to falter.
