I have used both a Pfaff industrial machine and Bernina in my drapery shop before retiring. I believe either of these brands would be trustworthy pieces of sewing equipment. I tried a Bernina sit down with bsr, and loved it...but both these brands were way out of my retirement budget when l went to find a quilting only machine. I'm happy with my light weight Bailey, because l can travel with it, use it in a frame, or at a table...but if you can afford the Pfaff or Bernina, you'd never wear them out. The problem with a sitdown, however, is you must still baste the quilt sandwich...something that gets less easy as you get older for the very large ones.
