I have an Elna with a large throat space and lots of bells and whistles. No stitch regulator, of course, because it's older. I have quilted up to queen sized quilts but find as I age, I just can't maneuver the quilt as easily as before. I have a small space for quilting. If you have the room, set a table behind your sewing table to avoid dragging. I don't have that capability, so I have reverted back to quilting in sections or "quilting by check" with a long armer.
