There isn't any magnets in this machine is there?  Reason I ask is look at the third video, at 1:30 there is a major ball deviation.  If it isn't a magnet it is some serious back spin on the ball after being spat out by Gene.  Owners are going to want to keep their balls clean and that playfield waxed as well.

The spin is from the spinning disc in the head, when the ball isn't locked it rolls back over the disc and is spat out instead of just dribbling out of the head.

There is one in the showroom at Zax Amusements in Melbourne for those looking..
