Other than the two that belong to members here (which I can state for sure aren't for sale), a couple were sold locally - I think the fellow "Finny" doing that cafe is one, and the other was someone out of Sydney, not sure if he's into the pinball forum scene (don't actually know who it was, just grapevine stuff).
You know, you would almost have more chance of securing one by buying out of the US and shipping - with the way things are there you might score one, and I suspect for less than it would cost to motivate anyone here out of their's.
Best of luck.
