Hey Tim,
I also moved to Tassie almost 3 years ago now.
I will say it is hard to find many pins for sale here, the one you are looking at is probably right for the current market provided all that he mentions is true. But I am no expert, and the market is softening a bit of late.
Also, just in case you are unaware...Haggis pinball are remaking Centuar. It is more than the one you are looking at though, just thought I should mention it.
Going by the 4 hour drive comment I take it you are far north?
