Machine is great, but I've had several minor issues:
-Ball eject didn't always work - fixed by bending diverter back a little
-Shaker motor doesn't work - waiting on replacement power board (thankfully rest of game works)
-Left front castle tower is getting stuck on larger tower and not returning to position (need to adjust)
-Moat VUK is starting to act up (probably just needs a little adjustment)
Not a repair, but be prepared for some work if you want to install mirror blades. The hinge nuts on my machine were torqued so hard into the cabinet that the ends flared. I had to use a long bolt and mallet to hammer them out and install replacement nuts. The fit of the blades is also extremely tight on my cabinet.
