I have the Pfaff Grand Quilter also on a 10' frame. I just got it last summer so I have only used it about 5 times total. I do like it, and I bought it used from a lady in my Quilt Guild, so it wasn't very expensive. But, if I ever can afford to upgrade, I will certainly move up to a 13-15 inch throad. The 9" is just too small, you end up moving the quilt after every row of quilting, then you even have to move the pantograph (if you are using one, which I do) because the pattern won't line up with the space you have to quilt in.
