I doubt it classifies as a "good one" but I have a little underwater version of the cannon sure shot. it's a great little camera for taking fish pics. I think it retails for around 150. I have used it underwater twice. One pic about 8" under the surface came out great under bright conditions. the other one about similar conditions came out poorly.

Probably a poor choice for the professional but if you want a camera for taking fishing it's a great choice and I highly recommend it.
