I have a 70 Elna Super - my favorite. Doesn't take that extra stitch that the electronic do and has the best stretch stitches. Second favorite is the Viking 1100 - has enough power to sew through 4 layers of leather for my biker friends, the real work horse of my studio. Least favorite is the Viking D1. It does nice embroidery work, but I hardly ever use it for regular sewing. I believe we all have our favorites for the type of sewing we do and what works for me most of the time is to keep them all. The other two machines are about to find new homes. I haven't used them in the last 6 months. It's hard to use 5 sewing machines, serger and long arm by one woman LOL. There isn't enough hours in the day.
