Well, I've thought of that, but there's a lot of factors involved, like
condition etc that will effect prices. If we pioneered an ebay title
posting format, then well, it would be pretty easy. Or alternatively, we
could only use those entries that have certain information in the title, or
yet another possibility - just use all "found" auction data, and make that
the "middle of the road" average. I'd be interested in something like this,
and could code the DB and app.

Good luck parsing this auction correctly <http://cgi.ebay.com/ws/eBayISAPI.dll? ViewItem&item=3074939557&category=3561>. ;-)


Between the typos and the combined auction you're in trouble. Also, you are going to *have* to deal with the auction descriptions, if only to separate out all the permutations of game and parts. A listing for Ultima IV that pegs an auction of just the disks with an auction with everything will royally mess up your rarity scale. Even if there is an app scraping eBay for the basic info, I can still see people spending a lot of time making judgment calls about where each auction fits.

I'm not saying it can't be done, but I think you'll spend more time hand massaging the data than you might realize.
