I had the BSR and didn't like it. It got really pissy randomly. ecmoore mentioned issues with red fabric... I had issues with pretty much anything. I learned to quilt with the BSR off. It takes getting used to, but I prefer quilting on my small machine without a stitch regulator. What I do like about my Bernina is she has a foot pedal free option. So I turn my machine sideways, press the "go" button, and stitch away sans non-me stitch regulation.
