There are a lot of great cameras in your price range. Nikon, Canon, and Sony all have models in that range. If you go to some of the big box store sites you can select a few and compare them side by side to see which one may suit you more. I just bought a new Nikon--I already have Nikon lenses so it is my brand of choice. I would also suggest going to look at them and see if you are more comfortable with the feel of one over the other. The other day I was in a store and they had a model on display, so of course I went to play with it. The buttons seemed to be akward. I did notice too that they package a lot of the cameras with a nice range zoom lens. 18-55mm or 18-105mm. Nice lenses to start you out and make your new camera a lot of fun. Good luck with your search.
