Lehman's has carried this machine for years now. Here is a treadle cabinet to go with it. I'm not sure that price is for more than the head, though. If anyone finds out, I'd like to know. Allbrands.com also carries the head. The head, by the way, fits most standard treadle cabinets. I like the quality of the Janome.

My 1906 Singer 127 treadle is showing it's age and the years of neglect it had before it met me. I am considering getting this head, which also does zig-zag stitching, for my treadle cabinet to replace the 127. I do use it from time to time, especially when the electricity is out.
