I've had a T1i before. I really enjoyed it, but something I disliked was the grainy-ness of the images are higher ISO's . seemed like there were still unwanted grain at ~600~ . it's been a while since i owned it. so i next bought a nikon d90 and loved it, everything about it except video mode. however i never owned a t2i, but i can tell you this, at 1600 iso on the d90, it would be "acceptable" meaning it looks still extremely nice still being at 1600. so i'm just saying i liked my d90 that i don't have anymore. hahaa
