Jim, other than the Harbor Freight's 14" ($49.00) cutoff saw, one thing you
might want to explore is your local adult classes in welding at your High
School. We have a class here that is very reasonable $ and we can use all
the great tools (plasma cutter included) for working on our car projects.
We also have access to a lot of metal working tools that I could never
afford. Just a thought.
