Update:
I did get the camera. In fact, I got an amazing deal such that I would be an idiot NOT to get it. Its a nice camera with 2 minor problems, and 1 major problem.
The minor problems are: lifting rubber pieces at various places. The pieces will need to be replaced. This is not a huge deal. The other minor problem seems to be associated with the battery grip that came with the body. When I leave the battery grip attached, the camera will unexpectedly and randomly lock up every now and then. Have to turn the camera off and on again to keep shooting. However, this issue has yet to happen when the grip is removed. So, this is also not a huge deal.
The major problem: Well, I actually started another thread here at RFF about the major problem. The previous owner wore cologne. Apparently, a LOT of cologne. The camera is quite, quite scented. I threw away the strap immediately. I've detailed my adventures with attempting to de-scent this camera on the other thread - "Scented Camera!" - and I am just now beginning to think I will win the battle.
I will continue to wipe down all plastic surfaces with alcohol every day or so. I then follow with a wipe down with vinegar. Then, I keep the camera in a box with two kinds of "odor eliminator" products. One is a zeolite based product in a mesh bag, the other is granulated activated charcoal in another mesh bag. After several days of these treatments, the stench is reducing. Then, with the replacement of all the rubber bits (which needs to happen anyway) I think I will get the stink down to a tolerable level. Also, with perpetual storage in the "odor removing box", I expect the stench to continue to diminish over time.
Now, the D700 itself is definitely a nice camera. Currently I hold my breath to use it, and I've tried some nighttime images to see how it performs. Better than the M9, that's for sure!
Thanks all for your opinions. I hesitate to say how good a deal I got, but it was much better than expected. Much. So I'm mostly happy. Just need to deal with the stink problem.....
