I have a Bernina 830 I use mainly but I have a Viking Huskavarna Quilt Designer for back up when I have to take my Bernina in for servicing since the dealer is two hours away. I also received a Singer 401 Slant O Matic for Christmas and love to sew on her. She makes perfect stitches. I love her stitches over my 830s stitches any day. She is so much fun to sew.
