While you may like to keep the old style foot controllers, a new, solid state controller will take the heat out of the equation. Sew-Classic.com has the solid state type on sale for $16.95. They have a tutorial explaining how to install the controller. I am replacing all my old ones with this type and they are lighter when using on 221s and carrying the machines to class. Each of my 201s has one already. Can't say enough good things about them.
