From what I have read about this frame, you can use any machine with up to an 18" throat. Husqvarna Viking Mega Quilter, Pfaff Grand Quilter, Any of the Bailey machines and I am sure there are others. I have a Bailey and love it's simplicity! I would love to have the Inspira Frame, the newest one, but there are other things on my list before I start over with a new frame
. Have fun shopping!
