Maybe get yourself a small collection of 5 or 6 EM's or early Solid State - that might last you a little longer. (Next best option if you can't move to Chicago and get that tester job at the Stern plant )
Seriously - maybe you wouldn't get burnt out on pins so fast if it wasn't one machine played non stop.
A small EM or early SS collection or mix, then rotate one in and out at a time to freshen things up.
