Hi Angus, I've bought the Pentax W20 a month ago and I'm very satisfied with it. I'm a kayakist (and yachtsman) and this is a very user-friendly camera. Menu's are self-explanatory. Fits snugly in the breast pocket of your PFD without any extra precautions. As regards image quality, I have not been disappointed yet. Even nighttime video shots turned out fine. Battery capacity is good even with flash, so you can get outdoors for longer periods without having to worry over charging the battery. Camera isn't very expensive either.
