Here are my reasons to want a treadle:
1. My grandmother had one that I used to sew
2. It does not need electricity
3. I like the "oldness" of it, recycling and reusing things past
4. I want the exercise as I have very limited leg movements
I don't want the featherweight, or hundreds more, just a good working treadle. I'll find one someday, when I have time and money at the same instance.
