I've taken 10-12 games to PATZ the past 4-5 years. All of my games are "players games". No collector's machines. So I'm not really worried about wear and tear on the playfields. A good cleanup, wax and a new pinball prior to the show helps. Plus, during the 3 day shows the games get less than 400 plays. The big pro, to me, is the challenge to never have a game go down during the show. I've come close - there's always something but each year it gets better. The biggest con has been loading those machines up the stairs out of a basement. Fixed that this year, new house is a walkout to the game room.
