I have 2 Pfaffs, one is a treadle (no IDT), the other is a1222E and it has the IDT. I really miss the 1222E, its in the hospital, so I piece with my Viking or Bernina. I have tested out the Janome with the accufeed , didn't like it as well as the Pfaff version; it just seems huge and clunky. I wish Pfaff would bring back the vertical bobbin system, I like it better for free motion quilting.
