Keep searching, Scott, Keep searching... It's that positive thinking thing...
I remember bidding on a CDROM of all the census's from 1841 to 1891, for the Outer Hebrides in Scotland, (which was not Kosher) and got into a bidding war which took it over £100 (about $200 at the time) when I had set myself a limit of £35, and won it - first time it went up and I did not expect to see it again... but I saw it up a few more times and the person I bid against got it for under £50, but it also failed to sell for £10 - the seller did give me access to a whole lot of other genealogical debris, for free (?) though and was also quite helpful with my research...
eBay is a minefield - if you come up against 2 people wanting the same item... I sold a Zep autograph on a roadies party ticket for £368 ($700 approx at the time) because it DID NOT have Bonham, but DID have Cozy Powell and Grant, with supporting gibberish - it was a piece of card 5x3", for gawds sake - I could have sold it for much more but I closed out bids from outside the UK - turned out the buyer lived locally and I hand delivered... phew... never expected it to go for much... biggest sale I ever had...
