Good camera between $400-$650?

I'm working on becoming a professional photographer (only 15, but interning for a photo company this summer) and for my upcoming birthday I need a camera! ( prefer NIKON or canon ) only care about good picture quality and battery life (maybe even fish eye effect)

Good technical quality I'd recommend the Canon t1i (which I own) or perhaps the t2i. Technical quality will be excellent if you know how to operate a dslr. The photo quality will be up to you.

Battery life is what it is. With my t1i I get about 600 or so stills with one battery.

Fish eye, that's a lens you'll have to buy. Keep in mind they're not cheap.

Personally I'm a Nikon fan, so if you want to get into dslr photography I would recommend the Nikon D3100 (400$), or a Nikon D3200 (699$) witch is a bit more expensive with EPIC 24 megapixels with standard 18-55mm zoom kit lenses.
