Calling Web Developers, I have an idea... Options

[McMark]

I had an idea that I can't implement, but I think is good. It would be cool if we could have a place where people could enter their used parts sale prices and condition. We could then get the mean value biased by condition to give a market value for used parts. There is a lot more complexity that could be added to the algorithm, but what do you think of the core idea?

How about something that scans ebay and records only the prices of parts that actually sell.. then you'll know the high end of things anyways. I do that often by looking at completed auctions, but that only goes back 30 days, so rare stuff is never there. If you made a dtatabase, after a year it would probably be fairly complete. Condition is another factor though, but you might be able to do something like olympic judging and throw out the highest and the lowest.
