I have the 440 and the embroidery unit which I purchased about three years ago. I love them both!! I have not had any problems with either. I purchased a Bernina because several of my “Quilting Buddies” had Berninas and they loved them. Also, the 440 comes with the BSR (Bernina Stitch Regulator) which helps you regulate your stitches when doing free motion quilting. The embroidery unit sews out beautifully. As stated in other posts, your computer has to be hooked up to the sewing unit to run the embroidery software, but I like it that way. You have a nice big screen to view designs. Before you purchase the 440, I would compare them to the higher end Berninas. I did but I chose the 440. Sometimes you can get a good used when someone trades up to a higher end one. I can’t compare the 440 since I have no knowledge of any other sewing machines.
