FYI to all interested, I was looking at buying ~2TH locally for 1BTC. I pay ~$.13/KWh for power. Based on the numbers I ran, 2.6TH won't make ROI for even 1BTC before they become negative in earning vs pwr cost. That was based on the best case scenario with a steady BTC price of $350, 0% pool fee, and a modest 10% increase in difficulty over 60 days.

If your power costs are lower, say <$.06/KWh, you could probably recover your investment, plus get free heat for the winter. Exchange costs notwithstanding though. Bottom line is that cheap power in certain parts of the world, combined with a painfully low BTC price has sucked all the profit out of mining any more. Undecided

I would offer .5BTC for it without PSU and I cover shipping.

Some people have free power and still only offering .5BTC and he pays shipping, that should tell you that ROI isn't worth it at that price Wink
