Campagnolo stayed in the game with quill headsets until the early 2000's, and for all I know may still. I bought a Chorus for my Trek 610, replacing a wonky Stronglight B10 (actually a bastardized one), in about 1999, and saw the same part in catalogs for a few more years at least. And Campy would not be wrong for a fine Italian frame like a Somec.

My guess is about $90 now, but I really haven't seen any.

It's still as smooth as glass.
