these days selling "old/ordinary" is becoming very hard, sure you can always find a person interested in a lens/camera (ebay perhaps), today went to a store in London (graysofwestminter) to buy a second hand lens and they offered 40 pounds for my lens (a 18-135 I rarely used it), they have a few selling for 140, not a bad business to run but people need to be desperate to sell for that price, anyway I went to buy not to sell, my advice is to keep as a second camera etc anyway best of luck!
if there is anybody selling a D700 I am all for it 
If I don't sell it I will have 5 DLSR's as back ups. I listed it here because Ebay is such a rip off at taking 9% plus listing fees. You're right, though, it will have to be a sweet deal for someone to pick it up.
I am also selling a D700. Below is the post I made on my underwater forums yesterday.
This is a used Nikon D700 full frame FX camera. Works great. Sensor needs a general cleaning. The camera has had 28,600 shutter releases against the expected life of 150,000 shutter releases so there is plenty of room for more use. Ill also include two 8 GIG memory cards. Excellent camera for someone wanting to upgrade to a full frame sensor but not spend a lot of money.
The camera has always been kept in its padded bag when not in use. I treat my cameras with respect.
Package includes:
(1) Nikon D700 Camera
(1) Camera neck strap
(1) Battery
(1) Charger
(1) D700 Manual
(1) San Disk Extreme III 8 GIG CF Card
(1) Patriot 8 GIG CF Card
Price: $1100
Why am I selling? Switching my Underwater system, which requires me to also switch topside (stock) accordingly.
Please message me with any questions.
