A good, cheap, Used DSLR would be...

I have a “mega zoom” point and shoot. It is 10Mp and I don’t enjoy it at all. So I am looking for a used DSLR that will last for about 2 years and will shoot in something better then jpeg. I don’t want or need to edit in photo shop at the moment but that is a possibility in the future. I have a stash of cash but I don’t want to spend more then $400. I know that I could buy something new for that but I would rather have something used, because I won’t feel so bad if I screw it up.
