I have a Janome 1600P db, Grace GMQ Pro frame and the Quilter's Cruise Control. The cruise control makes even stitches and I don't know what I would do without it. To be honest, my stitches will varie occasionally but I think that is more operator error than QCC. I depend on it so much that I haven't learned how to control my speed on the machine on my own. My sister has the Sure Stitch. She loves it but often has to adjust it with each quilt she finishes and it bugs her to no end.
