I am designing double sided boards that I am planning to etch myself.
Now, I want to start using pin arrays and realized that I will now need 
plated thru holes (where the copper lines the hole itself making a nice
connection between top and bottom traces).  Is there a way I,
a hobbyist with measly resources, can build a two-sided board
with plated thru holes?  I would like to avoid the following:
  
  tremendous equipment expense
  having to spend more than $10 per prototype board (outside the costs
     of blank PC board)

Has anyone tried this?  How does the big-wigs in the industry do it?

Send any responses to: climber@sol.UVic.ca

Any help would be greatly appreciated.
