I bought a kit to make some boards. It didn't work. It was about $40.

I sent some drawings to china and got back perfect boards in 10 days.
Cost was about $25. Back in the day a prototype set of boards would be 
several hundred dollars - thousands in today;s money

One can even get surface mount stuff assembled!
