Hi! I had the 440QEE for about 6 months and it wasn't for me. I could never get the hang of the BSR (not coordinated enough I guess) and I didn't like hooking up to the computer to embroider.
So I traded mine in last month for the 630E and am loving every minute with it. I love the piecing and embroidery. As for quilting it....I decided it was worth sending my tops and backs to my friends sister and have her quilt them for me. Much less stress and a much happier quilter :D
My only advice is to go in and really try it out to make sure you make the right choice of machine as they are a lot of money and you definitely want to be happy with your choice.
Have fun
