I'm not asking what sort of camera to buy, but I do want to ask something from people who have real experience with SLRs. What entry-level system/camera in your opinion does the best job with higher-ISO settings? If you needed a camera to use indoors without flash, and needed to go up to 800 once in a while, what would your choice be? Understandably so, this would vary greatly with the type of lens (a 50mm 1.8 will help out a lot) but for the sake of argument, you have to use all of these cameras with the kit lens they come with. Just curious.
