I've moved to a smaller camera/housing system and am selling my D300 with its housing. I'm also selling my ports, sync cords and strobes. This is an excellent system that has worked well for me.
Nikon D300 and Sea&Sea MDX D300 housing - $1200
Includes camera charger, body cap, manual, and camera original packaging.
Sea&Sea 10" dome port - $500
Sea&Sea flat (macro) port - $250
Double sync cord - $150
Single sync cord - $85
Sea&Sea YS110 strobes (two) - $300 each
I will sell all of the above for $2500.
Also selling a Nikon 16mm f/2.8 fisheye lens - $600.

Most of the images taken on my website http://www.divermaiden.com were taken with the D300. Take a look at the Underwater Gallery.
