+1 for JonesGear on both their website and via Amazon. Very quick ship.
There's also a bit of a price war going on ebay now with different sellers (well ... prices are getting more realistic I guess) for U2 Antminers, as I imagine a lot of people's MOQ orders came through from BMT and looking to sell off stock quick. I see U2's going for $31 when you include shipping to US and about $35 to Canada.
yeah the u2's are a lateral move from the u1's both do 2.0 gh pretty easy.
the u2 can get 2.2 on some hubs.. both need fans if you have a lot of them.
So a u1 at 25 or 26 on ebay is better then a u2 for 31 . for most people.
if you do not want a fan for cooling u2's are a bit better. if you want a smaller foot print and do not mind using a cooling fan the u-1's are better.
if you want to go for a nano fury 4gh a stick here is a link
