Quoted from PinMonk:It would be even better if a site like that had archived price history from actual sales so you could see the trend for a given machine you were researching. But I guess that's just dreaming...or is it?
Boston Pinball keeps track of Ebay sales... which I think is a bit more accurate for older games. but still.

It is nice to show a seller (that has an old non working game) to give him an accurate price when he has seen his Funhouse advertised on CL for $7k.
