I don't have any experience with the Pfaff, but looking at pics of the machine, it appears to be a "mid-arm" machine, thus after a little quilting, depending on the batting and the size of the quilt, you won't have very much quilting space left by the time you get halfway through the quilt. Have you looked into a Bailey? They have 13", 15" and a 17" machines, they're VERY reasonably priced, have a good reputation, and excellent customer service. When I have the room and the money, I'll get a Bailey.
