It seems to me some machine values are flat, they are around the same cost they were 12 years ago when I purchased my one and only machine, yet other machines have sky rocketed in price. I suppose supply and demand has created some of this but certain titles are ridiculously over priced. If you are referring to eBay prices sellers think anything with flippers is automatically worth 4k and if it's a top 20 pin then they go to 8-10k. I bet there are plenty of people willing to pay those prices...
