I have the same set-up. Got it a year ago. I have had to make the usuall adjustments with tension. I also tried it off the frame and had great stitching. Real smooth. I have quilted appx 12 quilts so far. 6 queen size, 2 twin, 4 crib. When I did the queen size, I turned it to do the side borders and vertical patterns because of the short playing field of appx 6". I am tempted to construct a table to recess it into for FMQ sitting down. My sister just got one with a Grace quilting machine frame. If I see another 1500, second hand, and a good price, I would concider buying it.
