Quoted from NPO:36 sold pins in about 3 years - literally selling a game every month.
Do you even play your games????? .....
You're under on your estimate as he's had some games more than once! I give him crap all the time about selling machines (jokingly) but some people like to play, some people like to fix machines up more than playing them and some people just like the hunt for the next machine! Point being everyone is different. The fact he sells machines quicker than my pinball drains is what works for him!
(note: in the time it took me to post this delt31 has sold two more machines )
