I have my grandmother's treadle - needs a new belt so I've never used it. A Bernina and a Pfaff which I use regularly. A BabyLock Audry for travel. A very old Singer that was a gift - it works great but weighs a ton. My last acquisition was a Singer that I found at a garage sale - has all it's parts and works great. I think it's about 40 years old. I'm looking for a Featherweight, once I get that I'm calling it quits.
Oh, also have the Handiquilter Sweet Sixteen for quilting.
