Having moved to a D4, I am planning to soon put up my two D700's up for sale soon. They both have the original Nikon grip, the Battery from a D3s (over 4200 shots per single charge), and I have the factory dual battery chargers for them.
Someone looking for the near ultimate wedding photography kit is going to be really happy.
I also recently picked up a slightly used d700. I couldn't part with my d7000 though. It's been a great camera. Like another poster mentioned. I keep a long 70-300 lens on it for extra reach as needed.
