I have three: Pfaff for general piecing and quilting and occasional mending, old Viking for quilting and a featherweight for piecing and to take to retreats. The Pfaff is too heavy to move from home to car to retreat or sewing work days with my group. The Viking is an old friend that does good meandering. The featherweight is light weight, precise and never needs much attention, plug in and sew. I am not a collector and I don't need or have room for more.
