One thing I've noticed is that Pinside sometimes gives the "median asking price" -- beware this does not reflect sale prices and can be really jacked up with people that advertise games at super hight prices to hook a sucker or attempt to elevate trading value (which can manipulate the reported median asking price). There are also retailers of new and used pinballs that list games on Pinside and I guess they've got to keep their advertised prices consistent with their outrageous website and Ebay advertised prices. I wonder if there should be a distinction on Pinside regarding for sale by owner vs. dealer/retailer?
