Yeah I'm curious how this thing shakes out too. $229 is a lot more reasonable for a camera that'll probably end up on the bottom of the ocean. $400 for a GP3 is nuts.

I have to laugh at people bagging on a waterproof camera because they can't plug things into it while it's in the housing....
thats a great price and at least they are available.
I agree too that you dont need to plug anything into the camera while in the water.
