The repairman and I are now on a first name basis (he's installed three new motors, an electrical board, a new belt) and now he has to replace the entire machine because apparently ours is a "commercial" Precor unit that requires the kind of wiring homes aren't typically equipped with vs. gyms (hence the burned out motors and other horrors.)
That said, take a look at this video clip. It's a commercial for a bank, but it's hilarious and has elements I relate to. My friendship with my treadmill hasn't been easy, either!
