i have the sq-9000 and i absolutely love it its so much smoother running than my old machine. the stitches are beautiful and im sooo pleased with it. ive had it just about a year and bought it online from a sewing center. i got a great deal on it and it was even cheaper than walmart at that time. i assumed buying it from a sewing machine dealer would give me great service rather than the blank looks you get at wal-mart (at least mine is that way) and so far ive been right.
to be honest i really havent had any issues with it at all. its been wonderful not like my last sewing machine purchase.
