I started out withh a short arm (Juki 98TE or TL, don't remember) on a SuperQuilter frame which was set up on a 8-foot office table. I found I could do more than 4 inches until I got to the end of a queen sized top. I made sure the design was no more than 4 inches and I never had to turn the quilt around. The electronic part went kaput after 6 years or so. It was actually cheaper to replace it a Babylock Q. Pro. At that time I decided to get a Grace Stitch Regulator installed on the machine. I replaced this set up with a Bailey Pro17E and Grace Majestic frame last September. There were a few initial hiccups, but it is working like a charm now....love it! I just ordered a set of micro handles (especially made for the Bailey machine) for it. Can't wait.
