Just as the title states, I went to fix a client's PC and he gave me a D100 with two batteries, user manual, and charger. I currently have a Canon XT with kit lens. Should I keep it or sell it? I really want a new lens for my XT but I want to shoot with the Nikon to see how it is. I definitely like the way it feels in my hand (even more than the XT). But obviously I would have to buy a lens for the D100 if I kept it. What to do?
