I ordered from Moo.com and UVCards. The quality of UV cards is much better than Moo. I'd suggest going with them. Moo is cheaper though and are still nice cards. UV cards just seems better quality and their strict printing guidlines give you the results you expect. Also, UVcards had a black friday deal where it was 50 bucks for 500 cards. Couldn't pass that up! Came out to about 70 bucks after the UV coating and round edges.
Here's a shot of my Moo cards. I don't have a shot of the UV cards yet though.
