Replying to Need Camera Help - Possibly Switching Brands

Alright well here is the story, I currently have a Canon, and my dad and brother are both under Nikon. Now I am considering switching over to Nikon because of the fact that I would have a few lenses I could use of theirs. I do not have very much money right now, so just looking to make the smartest move with my money. Ive looked into the cameras some, and I just feel like getting a D40/D50/D60 & D70/s would be a step down from an XT. If I switched, I would be looking at something like a D80, but those I would need to find some cash for.

Mostly what I can't decide is should I still with my camera, and buy a nice zoom lens & prime, or should I take a step down in the body and use some of my families lens's. I would prefer to stay with Canon, because their lower end bodies (my range) seem better than Nikon's, but Im tired of being the red-headed step child and not using the extra lens's.

Basically what I am looking for is to sell my XT & kit lens + $100 or so, and get a Nikon body that is equal/better than my Canon. Suggestions?
