Apparently, I am wasting my time on the 13" but I have it and like it. I have had it for close to a year, bought it used, got a good deal and haven't had any trouble. I just wanted to be able to quilt my own tops rather than send them out. It got pretty expensive and since I didn't have to spend time quilting, I could piece even more tops and then had more that needed quilting and so on... I have the stitch regulator and I recommend it.
