I have purchased 3 container pins. The important thing with any pinball machine is to check it out, play it as much as you can within reason, and make sure the price is right.

Dealers have to make money, pay staff, probably pay rent as well, so the price has to be higher than some looking to cover the cost for their container to arrive in Australia. Sometimes dealers will let machines go cheap just to keep the cash-flow going, or just to move some on untouched, but for better quality machines you will be paying good money.
