Try this link on how to do it yourself.  I bought the ranco controllers online (ebay or amazon)

I have 5 controllers I have been using for many years. From my experience, the Johnson brand
digital controller is a better unit. When I do a calibration (150 F), the Johnson units have been
more accurate. My Ranco units have always been at least 2 degrees or more off. I just write the
comp amount right on the controller. The Johnson units are also much faster reacting to temp
changes; I like that.
