Thanks Punkin. It gives me a starting point. I have found a couple for sale in the U.S. One in San Fran that needs work but am a bit worried about the whole shipping thing, cause I know it will need to come over in a container.
Not really sure if the sellers I have made contact with realise Sydney Australia is in another country.
I have seen the pinball classics site, they have some nice machines but they seem to do their own resto's and are quite expensive. I will touch base with them to see if its an option.
