My opinion, and experience is that as soon as you identify a piece of equipment that will really save you time and money it is your obligation to purchase it as a business person. When I built a tumbler I remember thinking I wish I could buy another machine that would save this much time. Same thing with the work truck, forklift, Air hammer, natural gas forge and induction heater. Good equipment that is set up and ready to use is worth the expense. Broken tools, excessive projects and clutter hold you back and sap your motivation.
