We have the flash one from Target that is re-useable...I think it was $20 including a roll of film. I was happy with the results we got from it on vacation last summer, although we didn't put it to any great tests; however, the underwater pics were clear and the flash seemed to add a little illumination. Besides underwater use, the advantage is that for relatively few $, you have a camera that is protected from splashes and sand around water, and can almost certainly be used more times than the comparable cost in disposables (don't the underwater ones run about $10?). We are keeping ours in a ziploc bag, because if the plastic case gets scratched in front of the lens, that blurring will always show up on your photos. For casual photographers on a wet vacation, this seems like a good choice!
