I bought a Viking Quilt Designer on a frame that has a stitch regulator. I turn it off. I too feel like I have more control without it on. I don't have a Sweet Sixteen but didn't really have the extra money to spend on one so I made my own with an old darning machine. I can't post a picture here but I'll start a new topic with it so you can see. It doesn't have a stitch regulator either and I do just fine with it. I personally don't think they are worth all the money.
