When buying don't plan on fixing it yourself unless you really understand
electromechanicals. They have many leaf switches and it only takes you
moving one the wrong way to really foul things up. First question I ask
people is what did they try to do. If they tried it usually takes 2 to 3
times as long to fix because they have forgotten what they did by that
time. Get references about anyone who supposedly is going to fix it. That
goes for all pins and games for that matter.
