So I'm beating the heck out of my XSi, and am starting to think that down the road a year or so I'm probably going to want to get a new camera.
I want to stick with crop-sensor. I think my main issue with the XSi has been handling of high ISO. It's barely usable at 800 and anything at 1600 is pretty much unusable. Looking at cameras like the 60d, 7d, Ti2... is there any difference in noise at high ISOs?
