That Canon Sure Shot Owl is a good option. There are also decent Pentax P&S cameras that you could get cheap. If you want something rugged, look for a Pentax Zoom 90 WR (I think that's the proper name) it has a zoom, I think 38-90 but maybe even 28-90, and it's water resistant (they won't officially call it waterproof, but I remember when we were selling them at the store, the Pentax rep told me about one that fell off the back of a boat into 10 feet of water and was retrieved a week later and still worked). They're pretty rugged so if the urchin drops it occasionally, it will survive. And it's big enough that the controls should be pretty easy to operate for small hands. Don't know what they're going for these days, but you might find one at a Goodwill.
