Quoted from EMsInKC:It's pretty intimidating to look at, that is for sure. Tons of relays and steppers. It scores to 999990 so you have not 16 score reels to deal with, but 20. It's a whole lot of game for an experience person to work on, much less someone who has never raised the hood on an EM before.
I agree about Grand Prix being intimidating. I almost didn't buy mine because of its reputation. The machine spent over a decade in a warehouse and was in nonworking condition when I got it. Thanks to the help from Pinsiders, it now plays great.
