I have the 10D.
Make sure you get some decent Canon glass with it, though, so add that into the price.
Also, I got the optional power-pack, battery grip... you can shoot twice as long, plus it makes the camera feel more substantial and look more professional.
One of the nicest features, which will also save you time, is the camera's ability to automatically rotate the images you shoot -- all verticals come out of the camera already flipped... nice!

Some people bitch about the camera's (in)ability to focus through the lens with non-Canon glass. I think those people are just fucked up, though.
I've had no focusing issues at all.
Plus, the autofocus is blazingly fast... much faster than I am, and I've been shooting for more than 15 years.
Get it... you'll love it.
