As you might know, depending on which threads you've read, I'm looking to add a camera to my roster this summer. I'm not really sure how much money I'll have; but I know it'll be enough. I've been seeing some very attractive offers on slightly used 300D's lately, so I was wondering, how much of a step back would that be, if any at all, from the 400D I've been using? Besides the obvious 6 vs. 10 MP's. I could budget more for lenses if I got this camera as opposed to others, so I'm curious to get an honest opinion from all you 300D users.
