I looked it up and it was $130 for two boards back in 10/2000.
They are about the cheapest board house that I''ve found and
the free layout software that they have is simple to use. If you
can squeeze your design into a double sided 2.5"x3.75" layout,
they will sell you two boards for $60 with a 2 day turnaround.

I used to do point to point work, but now I find that my time
is more valuable when the design has more than a few components.

Standard 0.062" thick board.
