I am debating whether I want to spend $600 on a stitch regulator for my Babylock QCP. I am beginning to do many more quilts on frames and am finding it frustrating that the stitches are a mess, and its been quite challenging to say the least. I was wondering, for those that have this device, is it WORTH THE $$?? Does it REALLY HELP with stitch consistency and overall ease of use? Does it act similar to a long arm sensor?? How does it compare??
