Ewa-marine underwater housings?

[jwurst]

Has anybody tried the soft sided Ewa Marine underwater housings for slot canyon hiking? They get pretty good reviews but I'm wondering how well they might hold up in the canyons.

I'm always looking for better solutions. Right now I'm using various hard waterproof cases for my dSLR's. They keep the camera safe but are hard to use in the water. I also have a Pentax W30 which doesn't produce very high quality photos.

CarpeyBiggs, if you read this, how do you haul your cameras? I really like your work, by the way.
