Best place to get a PCB manufactured?

Hello @r4bbl3d4bbl3 !

If you want a PCB on the cheap and with good enough quality, then go with JLCPCB: https://jlcpcb.com/
Beware, it does very limited PCBA service so it is fine only if you can solder your components yourself.

Another one is PCBWay: https://www.pcbway.com
This one also fully does PCBA service (never tested) and quality is looking to be better than JLCPCB but it is also a bit more expensive.
This company has been used by Gondolindrim for some of these PCB designs, including the PCB of the Austin keyboard.

As for plate cutting service @VinnyCordeiro made an extensive list in this forum, here: List of laser cutting services

I know LaserBoost and they provide very good quality plates, but they do only metal.
