So far I love mine. I also have a 30D the 7D replaced. It is a pleasure to shoot with. The only thing thus far that I'm not keen on was it seemed slow to auto focus in low light, football games to be exact. But being new to that, it could have been typical of those conditions. ISO is great, 8 FPS is great, I'm very pleased with the image quality.
There is another thread with 3
B&H videos going over some of the attributes of the 7D. You might look at them if you haven't.
I'd buy it again.
Oh, I forgot to say, my card reader is not UDMA. More shots that are bigger files -- UDMA card reader is on my Christmas list as download times were about an hour after shooting my son's football games.
