Ben and 
to Aussie Pinball.
You will find all the advise you need here - so don't hesitate to ask questions. Are there any titles you have earmarked ?
Thanks for that. The first two machines I would like to buy are:
AC/DC LE (new)
Lethal Weapon 3
Any advice on where I can locate these machines would be greatly appreciated.
There were a few ACDC LE's (NIB) being offered on eBay.
Try Kids Just Wanna Have Fun in W.A
Lethal Weapon 3 - Easy, just about every container that arrives has one. Watch for wear on cabinet and broken dome light. Good fun game and should pick up one sub $2200 easily.
