I have 2. One is a centennial badged. Picked up both at thrift stores for 20.00 each. They both sew great. Used to fmq on it until i was gifted with a 201. It is even better to fmq and has a drop in bobbin. Use the 15-91 for piecing and sometimes fmq. I look ar them and the others I have in my little sweat shop and ask. Who wants to play today?
