Have 300$ for a Camera... help

I have 300 to 350 $ to spend a camera for filming, and also for photography. I have been browsing eBay for some older model cameras trying to catch a deal in my price range but have not succeeded. Can you guys help?

Do you have a tri-pod and SD cards? What resolution are you shooting for? even 720p takes up a ton of space, or at least it does on my camera.

AA Battery powered or lithium?
