This used to be a good deal, but the problem is the new antminer s3's that are out are 0.766W/GH.
366 Watts/478 GH=0.766W/GH.
At 0.725 BTC a pop for these. 9 of them yields 4302GH at a price of 6.525 BTC.
S2's are 1.1W/GH, which is much more inefficient as well.
Taking 478/0.725=659.31 GH/1 BTC.
8 BTC I can get 5274.48 GH at 0.766W/GH.
4000/659.31=6.06 BTC for 4TH of 0.766W/GH.
Effiency is also worth a bit too, for being a bit more effient then s2's
s2's real market value is a bit less.
Real market value for 4 of these are probably around 5.5-5.75
BTCMy two cents.
Bump - Price drop of 0.1 to BTC2.05
I'll take BTC8 shipped to the lower 48 US States for a bulk purchase of all 4 units.
