I sold my 440 because the throat was too small for quilting (for me). I also have a Janome 6600P with a nine inch throat which I love, has all of the above features mentioned plus many more. It has more stitches than I will ever use (I have a few other machines as well) It is a good solid machine and dosen't move around but I have since put it in it's own table. The walking foot is built in so you don't have to buy one and comes with lots of other feet. Don't trade in your Brother whatever you buy because it is always a good idea to have a backup machine. The best advice I can give is "take that generic walking foot off your machine before you ruin it " Good luck with your search and please let us know what you decide on.
