A little later than the popsicle sticks (87 or so) campy came out with retrofriction shifters that work just like the simplex retrofrictions. They started in that year with retrofrictions at several price points, and continued with the C-Record retrofrictions through the early '90's. The theory was that "real" bikies
didn't want clickers. You can often get these shifters pretty cheaply on da bay...and get the benefits of retrofriction shifting without the giant simplex price...
