I think there are so many factors to pins rising in the new and used market that its impossible to nail it down to one thing. The values of the machines are based on what someone is willing to pay, and apparently people are paying. The thing that I find the most interesting is how regional the prices are. Some areas have guys that buy everything up, then resell at 40%+ on Craigslist. These guys dont even like Pinball, they are simply profiting.
