I've finally pulled the trigger and switched to mirrorless and thus no longer need my Subal housing for my Nikon D300. Dove sparingly, never flooded and works perfectly.
Subal ND20 with ND30 back for Nikon D300 - Includes GS 180 viewfinder ($1300 upgrade) - $950 + shipping
Also will include the pictured ball adapters, extra body and port o ring, sync cable for Inon strobe, and a lifetime supply of batteries for the moisture alarm. I will also throw in 3 subal zoom rings free as I seem to have lost the labeling, but I dove it with the 12-24mm and 18-70mm. New this is more than $5000 worth of housing available for a fraction of the price (the viewfinder alone is worth that)
Subal DP-FE 8 inch dome port w/ exr 50 extension ring - More than $1500 new. Some cosmetic scratches on the plastic but the glass is in great shape without any blemishes that would affect pictures. Extension ring is perfect for shooting with the above mentioned lenses. - $600 + shipping
Subal FP-117B - This is an older flat port that I've dove with both the 60mm and 105mm. If you have lens compatibility questions PM me and I can take measurements. $100 + shipping
Preference to sell as packaged but open to offers. Ports and housing are type 3 mount.
