Mary,
Congrats on the win!
My wife wanted that machine REALLLLLLY bad. Her father worked for GE in FT Wayne, IN for over 40 years. But she didn't want to bid as high as it went.
Before condemning the foot controller I'd wait till you actually get the machine. It could be something as simple as a broken wire in the cord. And cords can be replaced. I've done a bunch of them.
If it does need a new foot controller, just about any two wire controller will work. Sew-Classic sells some nice ones. I've got three or four machines now using the controllers she sells.
Again congrats on that cute little machine. Once you get it up and running please give us a test report.
Joe
