Therefore Fusion360 is the best bank for the buck, but there are others. As far as machine. Cost determines capability and quality of machine, and also quality of finished product. My guess for decent quality your are looking at least $10,000 for machine and another $1500 or more in tooling and work holding to get started. You could look at Tormach or Novakon for machines. I think some people have even used the little Sherline for jewelry type work. Sky the limit. Maybe look for a second hand machine to get started.
