I have one of these and have used it 5 times in the last 2 months. You can browse their site at http://www.aquapac.net/ I have the blue small sized one for a non SLR Camera. I am relatively satisfied for a $25 product as opposed to the $199 waterproof case for my Canon Digital A70 Camera. The picture quality isn't that great after some salt water splashes on the outside, but if you can wipe it off on your sleeve it's do-able. A little level-correction in Photoshop actually will compensate for the salt-water film on the outside of the bag. As far as the inside of the bag, I often found condensation as the day went on, but this is also correctable by putting in a silica gel pack. You can find these packs from a lot of consumer products that come with them... just save the pack and use it for kayak photo shoots! I think this is a great affordable alternative to buying a specialized waterpoof case for your camera or a submersible camera altogether.
