500 what?
If it\'s buckaroos, I\'d get one of these (if I was buying a compact...)
Canon G9
It\'s a cracker for the money - probably the best compact out for that sort of cash at the moment.
You might also look at a DSLR like a Canon 400D or Nikon D40, although you\'d most likely need a macro lens to match or better the G9 out of the box.
