A few more for PCB work: For prototyping work in the US, I've used http://ohararp.com/stencils/ http://ohararp.com/stencils/ for laser-cut Kapton stencils, and https://oshpark.com/ https://oshpark.com/ for PCBs. For professional turn-key work in the US, I've found Advanced Assembly (http://aa-pcbassembly.com/ http://aa-pcbassembly.com/) to be absolutely fantastic. They've managed to produce a pick-n-place automated process for low-volume fully-assembled prototype quantity PCB assemblies. The service is priced a little too high for amateur work, but its worth every penny for nimble startup work.
