As much as having Stern would be a good idea, really they only have a couple of models to show, and what about the rest?
The hobby side is dominated more by the older games, restoration and repair. I suspect that accounts for as much as 80% or more of the hobby.
Parts, dealers and games are more plentiful in Melbourne, so politics aside, it probably is the more realistic venue.
I'd prefer it in QLD so I could justify a holiday!
