Life is so much easier now, dirtypcb is a great service, I have a pile of
boards here from them which are far greater quality than anything I could
hope to produce at home or even in the lab I used to have. They're also
better quality than any of the local board houses I used in the past.
Having said that, I did hand manufacture fifty single sided boards from
photo laminate to completed product in one weekend using a Dremel drill
press for somewhere around four thousand holes and hand soldering every
component so it was definitely possible
