Considered the X3 from black arrow but unconvinced I will get a suitable ROI.
or would I be better off with other hardware ?
I am anxious to read the mining veterans' advice on this.
As far as I can tell, the S1 right now is the least expensive hardware. Direct from bitmain, 1.4 BTC for 180 GH/s, works out to less than $5 per GH/s (at today's BTC price - which - of course - fluctuates a lot).
Compare that to what's available for
IMMEDIATE DELIVERY. I suggest you stay away from "Pre"-ordering.
With the only unit I - so far - have bought from bitmain, I had a good experience. Paid for it Monday evening, received it Friday afternoon. Paying with BTC eliminates the hassle of Paypal and bank wire transfers (and that's the power and beauty of BTC, isn't it?)
If anyone can recommend other hardware as cheap (or even cheaper) available immediately (and so convenient to order online), I - too - would really like to know about it.
I hear 1 TH/s units are coming soon from Chinese makers. Anyone knows anything about those?
I am one of the unfortunate few, el cheapo I know. Of everything out there I would only consider S1 miners or old litefooted jallys.
This is my choice I will get one.
I am using U1 antminers to stack em. Can buy a couple a month with coins and soon more as my ghz goes up.
Then S1 is next, I see no other option in my budget
See the server power supply thread to power stacks of them you will save $ and fly with a little DIY.
