I haven't tried making a PCB for over a decade.

$5 PCBs sound great, but what might appeal to me even more is an associated robotic CNC and surface mount service to install all the fiddly stuff and source the 10-50 whatevers of each thing I need from an assembly house's yearly consumption of 5 million Xs.

Are there any services like that? Where small runs are possible without the massive cost effect if picking parts that are already in flow?
