I'm starting college again and my major is digital graphic design with a minor in digital photography. I can get through my first quarter with my 35mm manual camera and my P&S nikon coolpix L18. However the second quarter requires a DSLR camera and I'm at a loss as to which would be best. I have a limit of $500 so I can buy a really nice new one or a great used one. I'm open to both options. I've been looking at the Nikon D40 which seems very nice but I'd like some more reviews on it if possible. Ideally I really want the Nikon D3 but I can't afford $4,999.95. At least not yet. Do you have any reviews of the Nikon D40 or can you recommend anything different?
