I don't know much about digital camerass either, but my girlfriend is an amazing photgrapher. She is in the middle of starting her photography business, and her play around camera is a Canon Rebel XT. She can take amazing pictures of anything with it, I am trying to get her to take some of my tank because mine just doesn't cut it. But I would highly recommend the Rebel XT based soley on her experiences and the pictures I have seen her take.
