I have the following. Prices are roughly what I'm thinking for each in USD (but pay in BTC), shipping to lower 48 included. Can also throw in a riser with each card if you need one. I ran each of the Sapphires at around 310 Mh/s undervolted @ 0.95 VDC. The XFX was about 15 Mh/s less. All come with original boxes and accessories. I also have an AMD Athlon xII if interested.
1 Sapphire 5850 ($100)

http://www.newegg.com/Product/Product.aspx?Item=N82E168141029321 XFX 5850 ($80) (one minor issue with this card is that BAMT miner doesn't like it, but it works fine with cgminer - I think the issue is just that it won't report fan speed in rpm, only as %, and BAMT won't roll with this)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814150494(has a red hood, not black)
1 Sapphire 5850 Extreme ($55) (this one has a bjorked fan, but I'm 90% certain that all it needs is oil for the bearing - I may want to keep this as a spare, but let me know if interested. Can include a bottle of machine oil)
