I have a (new) 830 Bernina I use all the time. Also have a 350 Bernina that the kids use and I use as a backup machine for classes and when the big machine is getting updated. I also have the Singer I learned to sew on 55 years ago and an old treadle that was my husband's grandmothers. There are 3 more treadles hiding in another house on the property but haven't looked at them in years. When I first saw this question I thought I only had one machine.
Oops -- also have a serger.
