You are correct that it is "just a matter of time" before the D700 depreciates down to $500.00 for a used copy. I would not hold my breath thinking that the price will drop to $500.00 in the next year. Used D200 bodies are selling for more than that and the D200 has been out of production for three years and was only about $1300.00 or so brand new. Best guess would be you have at least a four or five year wait. Then again you might get lucky and find someone willing to sell it for that price. Good Luck and Enjoy your Nikons!
