Skittl, I was under the impression that the BSR only works on a Bernina, and only on some models. It ties in with the electronics. It definitely isn't meant to be used with a longarm, where the speed (stitches per minute) is much higher. Is it possible that the SR you tried with the handiquilter was a different brand? There are quite a few on the market to be used with machines on frames.
Sorry my grammar was poor. I have used the bsr on various berninas. I have used the tru stitch on the sweet 16 (a sit down, no frame). I assumed people would know I used the bsr on a bernina because that is what it can be used on. The tru stitch can also be used on some baby locks if I understand correctly, I haven't used it on those.
