You get good service from dave and his dongle is so nice. Now if he could just use his expertise and figure out how to put one on a vintage ( Just kidding Dave).

They already make something like that, mechanical or electrical beside the machine ball loaners. Take 100 or 100/500 yen coins and dispense 25 to 150 balls, either into your hand or directly to the shooter tray.

Slightly more complicated unit - has card slot also:
