I have the Pfaff Grand Hobby with the 9 inch throat but with a stitch regulator and have just gotten used to using it. The 9 inch throat is very limiting--I frequently have to roll the quilt after having done only 3 inches of stitching especially if the pantograph is relatively dense. I have purchased a Pfaff 16 sit down but it hasn't arrived yet but did quilt on the one at the store and liked it enough to purchase. Both have their place. By all means do purchase the stitch regulator.
