Bellsy - thanks for posting that but i really really REALLY hate what youtube does to video (massacres it) -
Here are some exposure room links that give you an idea how the camera and housing is performing: (not so compressed) - if you really want to evaluate the video - click on the HD options
The land shots here were done with the Sony HC3 (HDv on mini dv tape):

exposureroom.com/40d562c73c5e47b4808bef1403d7159f/The sony HDV to mini DV tape / generic housing solution is a good one - as long as you transcode in post.
Unfortunately the standard sony housing wont fit a WA lense - but that hasnt really been a problem for me with native 16:9 chips
Hope this helps.
Avoid memory stick and DVD camcorders like the plague ..
