Most of the equipment is readily available on the surplus market. I've
come across many of the machines used for fab work at liquidation and
foreclosure auctions of fab and prototype/design companies. Generally they
seem to sell for under $100-150, though a couple went as high as $300-500.
The hardest part of doing home-fab work would probably be building some
type of clean room.
Folks have been rebuilding tubes at home for quite some time now, and it
seems like it won't be too long before you see the same thing with some of
the more simple semiconductors.
