when all is said and done, you need ONE stitch for quilting - a straight stitch. Everything else is 'extra'...
and if you want to do machine applique, at least a zigzag is nice - so now you are up to two stitches...
frankly I use a 50+ year old Singer 301 slant needle straight stitch machine for all my quilting...
yesterday DH and I drove 200 miles round trip to pick up a Singer @1956 319w which I already love - has a gazillion stitches (with cams) is in a cabinet with bench seat and cost a whopping $25 (plus the gas to get there and back)....
