I have seen alot of these titles in QLD over the last 12 months for $2000 and $2500 maximum and they were in excellent condition.
Some titles in some states attract alot less coin $.

I have also dealt with Jason from OzPinball. I found him to be honest and reliable. Certainly a nice bloke with a nice family.
You can definately negotiate with him. Like any seller, study every inch of the machine and ask fifty questions. In this market, every seller should negotiate to a reasonable price that both parties can be happy with. It would seem that VIC sellers charge alot more for this title than QLD sellers do.

Also, go and see Brett from Gameworx in Brisbane (Boundary Rd). He has various well priced titles and he is also a fair dinkum bloke.
