I "think" (I might be wrong) Bernina is the only sewing machine with a stitch regulator. My Viking Sapphire 855 has a large throat so I can free motion quilt. Unfortunately, the machine will not do the built-in fancy stitches on a quilt. This is my second Viking and neither would do all the decorative stitches with the thickness of the quilt. Otherwise I am very happy with the machine .
