When are they accepting orders?
If it's this week, I may bite... however, one week may be the answer for whn I get my BFL gear... at which point I'll be content with my purchase.
If they allow me to order this week for a 90GH unit, I may consider throwing 30-40 BTCs at it.
Well, I would consider a bargain 30
BTC for 90GHs. I would buy +10 of those. 50
BTC I would think it is a fair price and I would still buy more than 1 unit, considering that would mean a 30 days ROI with x3 difficulty (27 million).
More than 50
BTC for 90GHs, I would think very well about it and maybe I would buy just 1 unit as a gamble. If the pricing is more than 65
BTC per 90GHs, I will pass for sure unless they could guarantee immediate shipping (which unfortunately is not how it works).
