I've always found pricing games to be difficult in the first place. Typically I consult Pinside, the actual ebay sales list that's out there, and fellow pinsides (including the OP in this case). Realistically, I always ignore the high sales and the low sales. They are called outliers for a reason. If my price is off, I know it because the only responses I get to my ads are the chirping of crickets if I've priced it too high or twenty quick responses if I've priced it too low.
I agree, those who are over pricing games make things "look bad". Quite frankly when I see an overpriced game that I'd like to buy, I make a fair offer, attempt to educate the seller and if we can't come down to reality I move on. I've had a decent looking High Speed near me that the seller won't budge from on at $2500 because "that's what he has in it". My advice to him...."enjoy it...it's your game. Just don't expect to get your money back."
In the end, if we all just ignore the high end outliers I think we will still find games at fair prices.
Just my two cents.
