an AA member, Devil Rider in Adelaide, has a nice collection of Zaccarina (and Mr Game) machines
DDtoys has the most awesome shed

I would love to play some Zac's very hard to find them out and about.

Also need to see Dan's shed one day hopefully.

Single best collection I have honestly seen was Nino's workshop! I know it is not technically a collection but they are all his machines aren't they?

Walking through his workshop was nothing short of Nirvana.....
