I have one on my Pfaff Grand Quilter that I use on my frame. Didn't really think much about it one way or another until the day the wire came loose. My stitches were all wonky and it took me forever to figure out why! Now I check it to make sure all the wires are attached before I start. And, of course, I've never found a loose wire again. So I'd have to say I like the cruise control but I got it when I bought the machine so I've never quilted on the frame without it.
