I 2nd the Nikon D40. Good entry level DSLR. It would be a good starter camera to help you develop your skills and photography understanding. And any lenses you buy for it you can keep when you want to upgrade your body if you decide you're really into it.
There's really no point in getting a super nice top of the line if you're just starting out. Its what I got, and I'm 100% satisfied with it. Does everything I need plus a lot more.
