I am going to buy another machine the two in contention are the Juki 1541 and the Cobra class 18. Your right similar machines. The cobra has a reducer on it that allows a very slow stitch. The Juki does not. The Juki has a beautiful back side stitch, however, I do not know about the class 18. So this is why I asked. I want a machine that front and back stitch looks good. Why, because I may make a notebook, the person opens the notebook and sees both sides. I want both sides to look nice. I have a cobra class 4 and with this machine there is a notable difference in the two stitches. I hope I have made it clear.
