I've noticed that geographic region plays a pretty big role in the value of the game as well. I could be wrong, but I've noticed that out in more rural areas, pinball prices tend to be a lot lower, and around cities, there's a bit of "pinflation" just for being in or near an area with a higher average income.
I live right outside of Philly, and I can tell you with almost complete confidence that a Barb Wire will sell for no less than $2K around here. If it's got a DMD and it works, regardless of the title, it'll sell no cheaper than $2K--and that'd be a "steal." Now, if the game were located out in Iowa or Wisconsin, it'd probably be half that, but here sandwiched between NYC and Philly, people think they can sell that dusty old game in their basement to pay off their student loans.
Deals crop up every once in a while around these parts, but you have to fight to get them.
