I'm interested in buying the Sanyo Xacti VPC-E1 (the yellow one) for snorkeling and taking with me on surfing trips. Does anyone know how deep the thing can go?

And I see it takes SD cards, which is good cuz they're cheap, but how easily swappable are they if the thing is wet? I know changing film in an underwater camera was a pain cuz you have to make sure the seal isn't damaged and the internal components don't get wet.
