I just got the same machine today! I've been sewing on a Brother CS6000i and had a lot of trouble doing free-motion quilting on it. So I bought the PQ1500S because of the larger throat area. After getting the tension adjusted, I tried free-motion quilting and it was like magic! I had such a hard time before and now I can do it so easily with no ugly loops on the back side! If I didn't have to sleep, I'd sew on that thing all night! I love my new Brother PQ1500S!
