Getting Rid of the D50 + all lenses, I'm thinking about starting over again, what should I get as a body. I don't mind switching from Nikon to Canon. I mainly do street shooting and people shooting cityscape and landscape shooting. I'm going to buy a prime lens, a long lens, and a landscape lens. I'm considering the following (all used body only) D80 v. Rebel XSI v. 30D. What do you guys think? Discuss.
