When purchasing an "as is" machine - remember that in addition to having the game "shopped out" to your standards, the boards will need to be refurbished as well. Depending on the manufacturer, this involves different processes. Connectors nearly always need to be done, filter caps and Bridge Rectifiers and then the various faults (if any) need to be attended to..
Good point; I should start reading some of those guides everyone keeps talking about.
