Hello Sarah,
You don't need to get get the actual Frister foot control for your machine, you can fit any make, the favourite make to get is YDK universal, not costly at all, if you need the harness and the control then you need to find a Frister dealer, what is wrong with your one? I can give you a list of sites for controls if you e-mail me.
