If you mean JUKI machine, I have one. The throat is only 9", but I have quilted a king sized quilt with it. It's been a great machine for me
As to the frame, I have mine on a Hinterberg Stretch frame. I love that as well. It is very sturdy and I don't get any vibration. I can easily take it down when I need to [although I leave it up most of the time]
