100% PCB as cheap as possible?

I am going to build probably a few keyboards (like 3) for people to gift to. Since 100% PCB is not as popular as ergo boards, Im having a hard time finding any.

Do you have any 100% PCB (aliexpress or gerbers for printing in a PCB service like jlcpcb) that you prefer?

My goal is to make it as cheap as possible.
