I think it depends on your customers. At Marvin's we have had a WOZ since they first came out - at one point we had prototype game #2 which was replaced with an early 5v production game. It was then upgraded to 7 volt.

There have been plenty of issues but it is still running and earning good.

When our Hobbit was on the way I was thinking we should just pull the WOZ but after looking at the earnings again decided against it.

The big thing not many have touched on is that women and children play WOZ a lot. And I think many of these people would not play pinball AT ALL if it wasn't for WOZ. It think it brings in new players and additional coin drop. Instead of just robbing from another game.

So if your clientele comprises a lot of women and children I would say get one.
