I want to start making some custom pieces out of aluminum stock that will
require accurate, clean cutting and don't like the results obtained by
using my chop saw.

What's the best route? Metal cutting bandsaw? If so, can I get by with a
low end unit like the one offered by Harbor Freight for $170? Will it also
be useful for future projects using say 16 ga. mild steel, etc?

Any input is appreciated!
