I have two Zaccaria's in the workshop - Devil Rider's and Farfalla. Both the best Gen 2 Zaccarias in my opinion. Pop in for a game a game or two !
I think my personal collection is just about where I want it to be. But aside from Paragon and Fireball, none are really up to standard. Good news is - the upstairs mezzanine will be converted into a "mancave" to house my personal collection as I restore them - available for anyone to play !
I think Michael Shalhoub or Alan Tate have the best collections. Alan Tate is rumored to have more than 1000 games.
Dan's collection is simply outstanding. Worth the trip alone (and his hospitality).
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.....
