I bought the Bernina 440QE with the BSR and I love it, although I now have a longarm with a stitch regulator. The BSR made learning to FMQ much easier, so to me it was worth the price. However I was buying the new sewing machine anyway, so the BSR itself didn't cost me that much. I don't think any quilting tool (or anything in life, for that matter) is "worth it" if you can't afford it at the time.
