I wondered about that. I saw a video and it sure looked nice but I know I would not want it because it would inhibit visibility. How do they price out verus the HQ sweet sixteen?
I am with Strad-
it's a very expensive set of training wheels. Save your money and just take the time to get used to how the machine feels. If you've done any free motion quilting at all you'll have no problem adjusting to the machine.
I would buy the machinger quilting gloves. Buy on the thight side. You want them snug like latex gloves. I am not a little gall but I wear the smalls.
Take your time to choose.
