I feel I need to chime in here.
I bought a Black Hole from Brian a couple of years ago and have since been down to his place to check out some other pins he had for sale at the time. Brian is a stand up guy and is very knowledgable in pinball and pinball repair. His machines are some of the nicest I have ever seen and would not hesitate to buy from him. Good luck with the sale Brian. I wish I had some extra cash lying around because I would buy your TZ in a heartbeat.
