I bought this machine a couple of weeks ago. Yesterday, I shadowquilted top-80/20 batting-and plain backing. I tried both the quilting foot and the walking foot... both are ok. It worked just fine. Since I have another machine for quilting that has a larger throat, I don't think the Brother will be my primary quilter. I do love the straight and blanket stitches on this machine, though. I actually went through all three layers with the blanket stitch with no problem except the top stitch shows a little on the back. I might have to do more tension changing. I haven't had a chance to try other stitches.
p.s. my biggest thrill with this machine is the needle threader. it is super easy
