Pinside Forums make pinball prices soar.. Someone mentions how great a certain pin is, price goes up a thousand. Someone posts a "Wanted" request, price goes up a thousand.
Or how this is the best drop target game. Or unsung sleeper, or rare and desirable. Maybe the next big game currently selling at a reasonable price.
Just went up a thousand, heck,maybe two.
I like the quote " I could get 10 EM machines for the price of one of those". Not anymore, Ems are now highly desirable and a thousand dollars has been added to their price.
