You can buy 5-6 and get close to 1th/s way before any product on the market has that kind of power
I ordered 2, and will buy a few more coins and add a third
At 3.15btc each they are a great deal
So for 9.45 bitcoins you have same hash power as the October jupiters
If you overclock them to 200gh/s you'd have 600gh/s
I don't believe there is anything close to that kind of power IN STOCK and that cheap on the market today
seconded. the antminers are one of the best bets at a profit, though 3.15btc each now may be too much. (2.75BTC would be more appropriate)
I bought a 4.75BTC and 4.25BTC antminers, and between them they have returned just over 4.9BTC.
