You are not missing anything that I see. They allow it to be as expensive as the person's needs requires it to be. However, I spent less than this machine's total cost on a bench top CNC machine that has a larger work area and can be easily adapted to do this functionality. I just have to swap the spindle out for the correct attachment.
