I have my used Fantasea FD-80 Housing system for sale for the Nikon D80. It's an acrylic case, depth-rated to 200', aluminum ports, fairly rugged. I've taken this on a couple of trips and done local diving with it, however it's in very good shape, minor wear.
Includes the standard port (fits 18-55, 18-70, 60 macro & similar), 5" dome port (15mm Sigma FE, others), and extension ring (combine with standard port to fit 105 macro VR, with dome port for 12-24, Sigma 17-70 macro and many other combinations). Also includes LED44 focus light and mount, handles, port covers, and flexible zoom gears that fit many lenses. A small carrying bag is included as well for housing.
There is also included an extensive collection of new spares; orings for ports and housing, controls, strobe bulkhead, etc.
The best thing is that I'm only asking $900/OBO for this great system. I also have a used Nikon body and two Inon z240 strobes available with the housing purchase (not available separately). This is a great way to get into DSL photography.
More information on the (now-discontinued) housing can be found here.
Lots of photos taken with this system are on my Flickr galleries.
