Re: Kodak DCS 660 Question
In all honesty, it's probably not worth it. Those cameras were hybrids of a digital back on a film body, and had a ton of issues and drawbacks. If you look at how the first few generations of purpose-built DSLRs that came out around that time and had better usability have fared as far as resale value goes, you'll see you would be lucky to get $150. The 660 was succeeded by the 760, which was itself a noticeable improvement, and even Kodak's 14N, which was a much more compact full-frame camera with 14-megapixel resolution that came out years later is barely selling on the used market for $500.
In this economy, it's not going to find many buyers.
