I really wouldn't hate seeing some company start using QUALITY "plastic", some kind of polymer to build their machines, QUALITY machines. Say what you want, but the firearms industry has been making a LARGE movement towards "plastic" framed automatic pistols for decades now and I seen something about an AR-15 lower reciever made of polymer not long ago...... If "plastic" is good enough to handle .45 ACP I think it's more than adequate to use in a vending machine.... Perhaps Oak, Beaver, AA and all the other big time machine manufacturers will make that movement in the future, complete polymer construction with perhaps the exception of the coin mech. Lower cost and will outlast steel 10 times over. Go ahead and google "Glock torture test" if you believe that "plastic" can't be tough. That said, these plastic machines I dream of would have to be made with quality in mind, not the cheap "craftmanship" that is Vendstar machines.
