I trade my 440QE for an 820 and cursed the day I did it. I t went up to Chicago for Repairs twice. he last time was the straw that broke the camel's back. Found out the 820 had to be babied and I don't baby my sewing macines. My dealer let me trade it in for a 550QE with no extra cost to me. She gave me credit for the extra bobbins and extra feet I bought and traded me for a new insert for my table. I love my 550. I never quilted on the 820 although that is one of the reasons I bought, for the wide throat. I also bought it for th extra large bobbin. I don't miss either part.
