Holy cow, I have always been sworn to Bally Williams games but when I saw an AC DC machine a few years ago I almost wet my pants. Have wanted one ever since, but even the Pro machines were too expensive. When the vault edition came out last year I nabbed a premium. It has been 4 months now and I play it EVERY DAY. Not going to load it up with toys, but had to do the thunder bolts, the cannon, the speakers, and the external volume control. BEST GAME EVER and YES I am a HUGE AC DC fan. Only bummer is no Bon Scott. I will have SR sign my instruction card at the TPF here in a few weeks..
