Nick, already ahead of you, found those posts while doing research and will be checking the screws and getting the bungee this week. I bought the housing through H2Ophotopros.com here in California, got it for $3999.00 no lights, no 80 port...for now. Turns out I know the owner Mike Luzansky, from one of the dive shops I teach for, and he needs some web work done, so we'll be doing some trade work, websites for lens and lights.
Great service, got the housing within the week.
Talked to someone at Light and Motion about transport for it and he said they do recommend the Pelican case, but that he simply puts the camera in a housing, the camera in a backpack and carries it onto planes. Just at the Maximum Allowable Carry-on limits. Looking for a new backpack now, an recommendations?
