I made the mistake of ordering my AC/DC PRO without a coin mech. For 2 reasons it was a mistake, firstly the coin door without a coin mech comes with a very ugly coin door front, meaning the coin slot is just plain with a black blanking plate and its just ugly. I am sure I can fix that if I buy a coin mech and get the steel blank plate removed and add the bits I need from AMD.

Also, if u ordered a Aussie coin mech to be fitted, interestingly, it WASNT fitted at the USA factory, it was fitted by Bruce/staff at AMD in Australia and it was a model that Bruce scources from Australia I was told, so it is likely you werent going to get a Stern mech etc, but a Aussie designed and used version.

The second reason it was a mistake not to get a coin mech, is that if I ever take the machine somewhere for a fund raising exercise, and charge say a $1 a game, I cant ofcourse do it currently cause i didnt get the coin mech.
I am told I can buy one from AMD anytime with the door bits I will need etc plus the full coinmech for $210 plus postage etc.  Next time i will just get it etc, but scratching up the $5950 plus $220 delivery, plus shaler motor at $200 etc was hard enough at the time than to throw an extra few hundred on the bill for the coin mech. Oh well, next time.lol

Should they come std with it from factory - NO, cause it adds un-neccessary cost and the home market doesnt really use it. I would rather STERN spend the extra money on the playfield with extra lights, features etc.
Should the game come with a shaker motor standard, YES, but its hard to get a brand new machine like the ACDC model at $5950 which was a bargain if u keep adding stuff into the mix.
