typical pinball customer age group I believe (correct me if I am wrong guys) is your 40-50 year old guys with probably 80-85% going to the home market. But guys like Strangeways could possibly refine this as he has a big customer base for restores.
Also you could check out the calendar to gauge the members ages as who ever registered and placed their birth date will have their age listed.
