Services like Express are nice, but, if you want to make a small power
supply, screw terminals, regulator, cap, diodes, resistors... it
costs $20.00 for each board.
then you want to make a PWM to analog converter, couple resistors,
couple caps and and an op-amp. Another $20.00
but, since each board is $20 and you have to order 3 boards, the cost
is now $120.00 for those two boards.
I don't know about you, but I can make two boards in an hour and save
myself the $100 on the simple projects.
