I have a BabyLock Coronet on the small frame (equivalent to HQ Simply Sixteen on Little Foot). I have done wallhanging to large throw-sized quilts. Yes, it's a pain to baste and move the quilt sandwich, but I keep it in context. I don't have space for a larger frame and I much prefer moving the machine to moving the quilt (for a throw size or larger quilt, especially). So I find it works well. I took a look at the HQ roll bars to which you provided the link. My concern is that then I'd really be limited to a quilt that is less wide than the frame. I'd rather have the flexibility to work on something larger. I do not have any regrets about my purchase.
