I've had my 7700 for 8+ years. It is a great machine. I've quilted large quilts on my 7700 without problems. I sewed together vinyl when reupholstering a chair. I also have a Janome 3160 QDC, which is a great light machine to take for sew days and classes. I previously had a Janome 6500. I have had no problems with my Janomes. Love them!!!!
