DTF,
There is no doubt in my mind that full sensor DSLR like the Nikon will give one a better image and there is so much good glass out there for these cameras. When I go out on a boat and hope to get whale or dolphin shots I have my Nikon D300 coupled with a 70-200 mm f 2.8 and it's a great package! Would be super cool to upgrade the body to a D800 ( I won't say it won't happen). But I can't see myself popping for $6k for a Subal housing or less for an even bulkier housing and going back to the Nikons for underwater. The Hugyfot proto housing in your link looks pretty nice and certainly a better price than I would anticipate from Subal. I should mention that you also need to consider a dome port which can be $1500 by itself.
It would be different if I were selling images or a professional.
95% of my shooting is free diving and the bulk and drag of a DSLR in housing is significant. I got my feet wet with an Olympus PL-1 in their own UW housing and was amazed at how decent the shots were. I consider the Olympus Penn series a significant step above point and shoot and with interchangeable lenses you have the option of going super wide to the point that a less than full frame sensor still gathers more of a field of view than necessary. I moved into a PL-3 which clearly provides better image quality than the PL-1 and now I am curious about the soon to be released Olympus OM D. Focus speed and shutter lag have really improved on the smaller cameras but they can't come close in high ISO quality compared to the big boys; at least that I am aware of.
About the same time my brother got the shot of me in the above post, I got this shot of him. (He had the good lighting and I was stuck in a back lit situation but decent quality, IMHO from a much smaller camera)
