I just sold mine after 4 years. I'm one of the 7,5v boards victim, 3 months in I was about to sell it even for a loss, I had boards dying one after the next one.
I bought the 2.0 kit and installed it, it changed my life, hadn't have to lift the playfield a single time after that.
If you set the outlanes on the easy position, the game isn't that hard. It doesn't mean you will ever see the wizard mode, you might not even melt the witch but you will have lots of fun playing that game as it has so much to offer
Comparing WOZ to TS4, is actually interesting, it shows the huge gap between what JJP promised they would always deliver and what they ended up delivering.
