Homebrew PCBs

Scott,
Yes I use them also, recently got some samples from Mill-Max they are <
40 mil and can accept a standard IC leg .
I've been using "high" IC sockets for years and soldering top and
bottom.  I also use the Harwin pins for Via's they are rather big
but very easy to use.
Through hole plated would be the best, but I know it's not possible
without a lot of chemicals and tanks and then the hassle of renewing
all.
