That's very true. The Gottliebs were very reliable, but most operators were "burned" from unreliable sys80 machines. Most would never buy a Gottlieb again. Ops went back to Bally/Williams because of the Bally name, and the choice of good licenses.
Heaps of them around though. You mainly see them by themselves in pubs etc. Usually Shaq Attaq and Rescue 911. 
What was the pricing difference between NIB Gottlieb sys3's and Wms/Bally back in the 90's?. In Australia that is.
I don't know NIB.
The last machine Dad bought as an Op was GTB "Street Fighter II". It NEVER missed a beat, in fact the only issue it ever had was during transport to its new owner in SA (to a member here !).
I know that Bally/Williams machines etc were much more expensive than system3 machines
