Other than write speed, they're all the same until there's a problem. I had a problem with a brand new Lexar 512 40x card, and they took care of it immediately. Even had the customer service manager call me the next morning to make sure everything was OK. Because of this, Lexar is all that I use.

Dennis - the link brings up the price at $120 right now (4/19 a.m.). Still a good deal but not that good!
