I have owned three of these titles. Wizard of Oz still stands out as an incredible achievement and the one machine I think about re-purchasing. Many people are unable to get past the theme or some of the ill-will that the company has caused in the past. But if you are unaffected by those factors, there's no denying that the machine remains unsurpassed in many respects. (We'll see about Dialed In.)
The shear number of toys and flippers. The number of shots. The excellent integration of theme and play. The unusual features not seen on any other machine. The unreachable depth of the rules. It is a lot of machine.
