For an inexpensive waterproof camera, look at a Sea & Sea in addition to a Nikonos. In this case, I hate to say it but you may well be better off getting a digital. Olympus makes some very nice waterproof digisnappers with a reasonable zoom built in. The other option would be to look for a housing for an SLR with a dome port that can take a reasonably long zoom. That, however, will set you back some serious $$$$.
