I really don't see how these sit down sewing machines work. I have quilted for over 25 years quilting on my Bernina 1530. I have done numerous queen size quilt, won many awards and successful sold many of my quilts. I constructed support sections around my Bernina that supported a quilt of that size. Those tables in magazine ads do not show any support. That is why so many people have gone for the frames. I can understand a larger harp but I had no problem with rolling up a quilt to the center and working my way out quilting as I go. Good luck with your final decision.
