I have one and LOVE it! I keep trying the new stitch regulator they have whenever I go to my dealer's store, but I don't really like it. If you're already used to fmq then it seems too choppy for me, and one more thing to think about. I did spend a couple of days working out the tension thing, but I just saw this video
