Well, since you already sold your video camera (bad choice IMO) the new t2i seems to be the camera you want, you can buy an adaptor for nikon lenses on a canon so if you have some good glass, just cop one of these adapters:
Not sure if that's the most legit kind, but something like that would make it so you don't have to buy any glass.
Now in the case that you don't have baller glass (which if you have multiple lenses that seems like t would be untrue) id start all over with canon and cops some nice shit.
But in an ideal world, you wouldn't have sold your video camera/would have upgraded with a real video camera, but that's just me.
causwell, check it out.
