  What are you folks using
  for via inserts on homebrew
  double sided boards?

  I had some Mill-Max
  http://www.mill-max.com
  0566-2-15-15-21-14-10-0
  or
  0566-2-15-15-21-27-10-0
  pins that worked quite
  well but I have run out.

  These are tiny gold plated
  hollow pins with 0.039"od
  and accept wires from
  .015-.021".  They are  .138"
  long so they stick out
  of the back of the board
  and make it easy to 
  solder to.  On the top
  of the board there
  is a nice lip on the pin, but
  you have to be careful
  when you solder to the
  top lip so that the solder
  does not wick into the
  hole.  Note that there
  a lot of other variations
  of the basic variations
  of the 0566-2 part that
  have to do with the
  coating (gold or tin).
  I guess all of them would
  do the job.  

  http://www.findchips.com
  search on "0566" shows that 
  Digikey has them as a non stock item
  requiring a 1000 purchase
  for about $100.  That would
  last me a lifetime.

  Anyone else have a better
  source, or a better or cheaper
  via insert?
