What Camera Should I Get?

I'm looking for a camera that I can shoot models outside and inside with. It needs to be around $300.00. Great mega pixels and also very good at taking pictures in low light and in bright light. Also a camera that will still focus if I shake it a tiny bit. I just need a little help deciding which one should I get for what I'm going to do with it. I'd kill myself if I went and bought a camera that didn't work!
