My reasons are similar. For quite a while I used the ExpressPCB prototype
service to get three 2.8"x3.5" double sided plated through boards (no solder
mask or silk screen) for $60. But eventually I found myself going through
all sorts of contortions to make my designs fit that size board and finally
realized it was limiting me too much. Solderless breadboard works fine for
some things but not for noise-sensitive or high-current applications, which
is what I'm mostly doing these days. I tried making a soldered breadboard
but there are just too many components that don't fit the 0.1" grid. It
quickly becomes a major hassle. Mistakes quickly get too costly if you're
paying hundreds of dollars each for prototype boards. So I finally decided
to bite the bullet and get set up to make one-off PCBs.
