This was the exact issue I faced last month. After very extensive research, as well as my bias towards the D700, I purchased a good, solid used D700. One consideration you might take into account if you go the used route: an extended warranty. There are some great deals now on nice used 700s that didn't exist even four weeks ago. I decided to pay a little more and went with an established photography dealer so that I could add a two year extended warranty (added $99 to the bottom line cost) So that gave me 30 months of coverage. There are only two extended warranty plans I would ever purchase: cameras and computers. I would also add that the issuer of the extended warranty makes a big difference: who is going to do the work on a damaged DSLR? I've read a few horror stories some have experienced from shady warranty operations. A little background check goes a long, long way to keep a buyer happy.
