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.
I used the BSR on my Bernina quite a bit until I bought a longarm. I loved it! I also have a SR on the longarm and personally would not be without it. There's so much to concentrate on that I need the extra bit of help that the SR provides.
