Paul, I was looking into prototype board costs and found a website called PCBcart (PCBCART, Prototype to Production PCB supplier from China).

They are based in China and made INCREDIBLY low-cost circuit boards. I punched in a quote for a 300mmx400mm (12"x16") board with 140um (4oz) copper, double-sided.

With a 15-day turn-around, they will produce a SINGLE board for 87 bucks! The best part is, the vast majority of that cost is "setup fee" which you only pay 1 time no matter how many boards or how many orders you make. It is crazy how little they charge for each additional board. 5 boards were 45/ea (including setup) and 10 boards were 40/ea.

So if 5 people were interested in making copies of this controller, it could be done for 45/person. No routing required. No drilling required. Plated vias, double-side copper.
