Well, I love my Pfaff - it has the built-in IDT (walking foot) for quilting (no separate walking-foot attachment required). I had a combo Brother sewing/embroidery machine (LB6800 - same as SE400) but it wouldn't quilt correctly - even with a walking foot (stitches irregular; had problems going thru multiple layers).
Pfaff has their Ambition line for under $1000 - and you may find an Expression on sale right around $1000. Lots of pretty stitches (and pretty machines!) and great, even stitches.
