You have already spent too much time on that obsolete coin
mechanism. Place an order for a Coinco for $35 to $50 bucks, and
spend your time on more important issues of this machine. You will
find yourself ahead in the long run!
I may do that in the end, but I wouldn't want to rob myself of a learning experience. I also have more time than money at the moment.

Thanks for the suggestion though, I will keep it in mind.
