You were very lucky. I have a Nikon F3 (one of the last and almost a virgin - don´t ask -) and a D200. I was interested in swapping the lot for a D700 but the dealer told me that there was no way that he could take either camera as part-exchange... how old can you become at such an early stage of life?

Hi, here is another story - I got more cash in 2007 for my mint black Nikon FM3a than I paid in October 2005
However these above are exceptionally good deals. Normally I miss same money when sell equipment. For example, I missed $500 on my Sinarback 54M after 10 months of use (only 1200 clicks), and $600 on white Macbook 2.4Ghz/4Gb/250Gb with spare battery after one year of use.
Run to sell your film gear, you will find it later in museums.
