Group buy - Chip whisperer lite blank PCB's

Just wondering if anyone would be interested in doing a group buy of some blank PCB’s. Im a bit of a tinkerer so would love to have a crack at building one myself. I priced up the boards with the supplied specs from pcbway and its not going to be worth it for just 5 boards however if we were to get 40 boards the price drops considerably. Perhaps anyone thats built one themselves could recommend a pcb manufacturer out of china?
