HI Roger, I have researched the price to the point of exhaustion. Prices on all the various sites vary somewhat but ebay has the lowest. KEH is my preferred source for used equipment but their price for the D2X/XS is significantly higher than I can get elsewhere. The median is right around $1000 whether it is by auction or buy it now. The sellers are not stupid. They know the market.
I do want a good, clean, unmarked example and I want all the goodies that came with the camera when sold new including the box, manuals, batteries, charger, cords, etc. This is fairly rare in the used world. It's hard for me to understand why someone would loose the manual or dump the box. But that seems to be the case. I'm willing pay more for the complete kit.
Anyway, $800 for the D2XS I have not found except for a couple of beat up examples. I'm not interested in those even though they probably work fine. But they violate my sense of order and aesthetics.
