I haven't seen hardly any large home collections. As far as commercial guys go, Nino's for sheer scale. Rob at BCW has a large collection in mostly very very nice condition machines from a good spectrum of era's.
Would love to see a few pics of your collection cavey if you got any shots.
I will find a thread that had Apx 40 or more DMD machines set up at the time for you. Collection has grown since then but it will show most of the DMD machines I think. It won't have any of the new Sterns in it but I can take some photos of them later if required.
Really hoping for other people's photos or stories of what collections they saw and their thoughts.
