Making a PCB is pretty cheap, even making 10 PCBs costs around $15 nowadays. I usually panel my PCBs so I fit 40-100 in a batch, depending on size (and then only use one).

I usually share my designs, the ones I've uploaded have links to the manufacturer where you can order them, though I haven't really done assembly on any, yet. I might, if any design has people interested, though.
