I have a PQ1500s and I just took it OFF my Grace frame a month or so ago because I was VERY frustrated at the lack of quilting space. If you are only doing a small baby quilt, it would not be bad, but once you start rolling up a larger quilt your actual work area becomes about 4 inches wide ! This makes doing anything detailed extremely difficult. Also it is worth mentioning that I started getting back pain WITH the frame that I never had before, because I was having to stand up all the time to quilt. Since returning to my table and sitting down I have had no more back pain. I just got a table that was the proper height for me to not have to hunch over.
