Hi Sarah, welcome to the forum. From your extensive list of interests and your other post about machine aquisition I would guess that you are already operating some form of business. CNC machines in particular have made vast steps forward in the last 20 years. Older commercial machines can often be purchased quite cheaply (my friend has a 30 year old cnc mill and produces some fantastic results), but generally I would say that the newer machines are more intuitive and user friendly. good luck with whatever you decide.
