All of these cameras are excellent options for you in my opinion. As for megapixels don't ever get caught up in that too much. Higher simply means that you'll be able to make larger prints with better clarity or you will be able to crop down a picture and still get the same quality. But many times you can become limited by your lens.
I feel that I've given you a few options here that are pretty sound. I've listed hyperlinks for the specs and low prices. Check it out.
Good Luck
