I had a nice long reply to the group, (covering two posts). But it
seems yahoo decided to screw up my message. But the gist was
the cost of producing prototypes at home or sending away. I am not
too concern at plating since I am thinking of buying a prototype
plating machine. I more worried about making the holes conductive.
