Every chance it will come up for sale again Marty. Big $$$$$ for that particular machine though considering the playfield wear and faded backglass. There was also a machine that was sold down Wollongong way about 12 months ago that looked very similar to this machine - wonder if it is doing the rounds????
I think there is a Superman backglass for sale in the US on Mr Pinball Classifieds. Don't know how much and it would be a PITA to get it delivered but.......
