If you really wanted to step up your game you should consider looking at one of the "prosumer" DSLR's .. like a Rebel XTi kit. It may be more than your budget, but it may be a better investment.

Cameras like that are top-sellers for a reason.

Personally, I don't think you say, "What's the best DSLR for $800?"

If you're going to research cameras, find the best camera that meets you wants, needs and will help you advance your skills ... find the best deal and try to afford that camera.
