Hello all. I believe this question was posed before with many people saying the 6600 would be wasted on a frame since it has so many desireable features unnecessary for frame quilting. Aside from that, would a 6600 be any less desireable or effective than say, a Pfaff grand quilter or a Juki which have equal arm lengths (9in.) to the 6600? If a 6600 would do OK on a frame, what frame do you all recommend?
