I have a mid arm, Handi-Quilter 16 on a frame. It uses a "robot" carriage that takes orders from a pc to move the Hq16 through a quilting pattern on the frame. I need that kind of system as my arms, hands, etc. can't handle it, and LA is too expensive. I bought the system used at a very good price; it meets my needs.
But, no, I would not consider LA as a business. I'm retired and I don't want to "Have" to do anything - and it is hard work.
