The other thing is (from my VERY limited experience) we kind of miss out on the great restorations that r done in Europe & the US (eg. beautifully restored Shadow playfields professionally sprayed with many thin coats of poly). Here it's a bit of cleaning of the metal trim with a harsh polish & a few rubbers changed & the machine is called "shopped" (whatever that means). I'm sure there are some good techs around though - you just have to know who. 
Actually with Strangeways & El_timbo86 - US & Europe are missing out on the quality that the Aussies are turning out - Happy Australia (Pin) Day!
