WTB HashFast, or power effient gear at ~1W/GH or better

[lightlord]

I am looking for power efficient gear, post your prices, I may be interested.

I am also interested in potentiality trading my Antminers over for power efficient gear if that's a possibility, or
trading my GPU farm over, I have a bunch of 290,280,270X, let me know thanks.

I do know antminer can run at 140GH/166 Watts, with undervolting, but I am looking for 28NM stuff as in the future
they can with undervolting, underclocking go to much better levels.

as you already know i have [WTS] HashFast >400GHs Bitcoins Mining H/w, in-hand in Australia - https://bitcointalk.org/index.php?topic=610629.0

apologies for the cheeky plug but I also have some SP10 currently held up in customs this weekend. Should have them in-hand next week. Will be looking for 9btc and above for each ~1.4THs (1250W) unit. i know, steep..

Cheers,

Yes it doesn't really make sense to spent 9 BTC on 1.4 TH.

When I can get 180GH antminers and underclock them to 140GH at 166Watts.
10 of em gets me about 4.1 BTC, under half the price.
