I have a White Rotary treadle that I've had several yrs, just not used it until 2 wks ago. Been using it every day to make quilt blks. I love it, runs so quiet and makes a great stitch. Don't let anyone "haul it away" for you!
I am also trying to get a Singer 66 Red Eye running, but it sounds pretty rough and looks very worn. Not near as good as the White. Also going to get a Davis Vertical Feed moved into my house (from garage) and get it going. I think I'm going Amish in my old age!!! It is fun playing with these machines.
