Is that called Zagame's now? If so I have been there before and there was a TSPP in there, but I didn't play it as I was about to head off to the Bushfire Aid Meet and Greet and knew I could play one there. Ironically I didn't.
The guy didn't want to sell, he just said $20K to get rid of you. You are right, you can get two better ones for that price. And most operators these days don't seem to care if the machines are working properly or not as it is not worth their time to fix them.
