Ok, I was contacted by a local guy looking for his first game. After some discussion we decided what would be right for him based on what games he wanted, and what cabinets I had on hand.
He selected a Frogger cabinet that had been converted to "Darwin 4078". He further selected an NOS Road Fighter artwork kit that I had "in stock". For controls he selected one 8-way top fire, one 4-way, 4 buttons and a single spinner, along with a USB port on the front of the cabinet.
And since I simply can't let customers have things that I don't own myself, I had to order an extra set of top fires for myself, an extra keywhiz Max, and will probably order an extra Oscar spinner.
