I had bought one years ago off ebay. I got to sew with it for a for a day and it was a dream! Then nothing. Called around, had people look at it. The end result was bad electronics that were result of poor manufacturing with soldering and placement (should say ‘misplacement’ of board innards). The short time I sewed with it, had me wanting the design as it was so natural to be sewing with the orientation of stuff. Now, If someone could just make this deign as a non-computerized AND treadle friendly I would be first in line to pay big bucks for it.
