Any stance you care to share on Bitmain? I went in for one of the new S3 miners. Seems like a nice option for individuals but perhaps not ideal for the big boys.
I met the guys from Bitmain, and know people who are happy with their S1 and S2's, but we don't have any. Another company I think may be a great option is Spondoolies. Spondoolies will have pretty good power cons., but the ship date isn't now like the S3's... These are all things to take into consideration and need to be weighed by whomever is doing the purchasing.
