Pentax has a nice little P&S waterproof. Works awesome for snorkling, it says 10 feet, but even at 22 feet it didnt get water inside and still took great pictures, its nice that the flash will work underwater if needed still
I'm a little iffy about the enclosures for the dSLR's, one little leak and its done. Not to mention its a bit hard to look through the viewfinter with the enclosure and goggles on. its hard to impossible to set some things once its in the case, none are really made for the flash to work, etc. You can tell that its deffinatly an afterthought, as as such is missing alot of usability.
A standalone waterproof dSLR is pretty pricy though.
