I paid 710 for a diamond plate playfield one a couple of years ago, but it needed some switches and tweaking (and a new display), also has a gouged up backbox that I need to fix someday. At the moment I am probably into it for about 1100. There is one for sale where I am (Florida) on Craigslist that does not look to bad for 1150. I almost considered buying it to switch the backbox and had him down to 1000, but decided to pass.
One of the best games I have had, I would pay more for a nice one if it came my way.
