I use a Juki TL-98Q machine on a B-Line frame. The machine is perfect, quiet, and a workhorse. The frame expands to king size but takes 2 people to do it. I have a quilt in it now that is 110" X 110".
I plan to sell the frame eventually and buy a New Joy that I played with in a local store. It seems smoother and lighter weight than the B-Line.
Happy quilting! :wink:
