I have had 2 of these - one in very poor condition that I eventually parted out, another in good condition that I cleaned up and sold.  As much as I love old school Sterns, O1 was a game I just could not get into.  For me the novelty wore off after a game or two, and after that I could not see the point of playing  game which has close to zero control over where you shoot the ball.
