Are 2nd hand D700's overpriced??

1100 pounds is about $1700 Canadian, which is a bit high for the prices here, but then it seems like the UK is always paying a bit more than us.

Bottom line is, the existence of the D800/600 doesn't change the fact that the D700 is a great and reliable camera. Also the ability to shoot 8FPS is an added bonus. So, I'd say it's about right. It will fall in time though like all camera prices.
