To be honest, I wouldn't even bother buying the overpriced skeleton housing.
Just do what I did with mine - take the standard waterproof housing and drill/dremel holes in the side to be able to access the appropriate ports. I knew I'd never need to take my camera into an environment where the waterproof case would be remotely useful - and if I ever do change my mind I can just buy a new waterproof case for the same price it would have cost me to get a skeleton one.
Just remember - measure twice, cut once. Something I learned the hard way!
