i've already tried to make this jump once about 3 or 4 months ago, but the company screwed up my order and i never got my d50, i wound up with a refund. but i'm thinking i want to make the jump again. but i think i'm going to go with a canon this time. my uncle has one of the orig digital rebel's and i've played around with that enough to know that i def want a dslr, and being able to borrow/share lenses with him is why i'm thinking about going canon. i'm leaving to go on vacation to dallas next week late late wed/early thurs and i think i would like to try to get one before i go. would a used rebel xt be a good first camera to learn with? is there anything specific to ask about a used camera, other than general condition, and how many shutter actuations?
