Everything you could ever need for anywhere between $10 to a couple thousand.
While a high megapixel count is nice it isn't the be all and end all, a larger sensor improves the image significantly.
The next big thing is lens quality. Ignore digital zoom and only count optical zoom in your consideration.
My personal preference leans to either a Canon or Nikon 3/4 body either new or re-furbished a spare battery and a nice lens or two that fill your needs.
