Ok, just found something about the XTi that bothers me, no built in wireless flash commander....
Right now w/ the D70, i have a SB600 flash (it was like $175) that can work wirelessly w/ the built in commander (popup flash)
Looks like on the Canon, you need a seperate wireless flash commander (or an additional flash on the shoe) to go wireless, that right there makes the camera cost an additional $250. That just sucks.
