That said, I've seen very few of the hybrid-style bikes that had broken headshocks... The first thing I check if I see a sagging front end is for a schrader valve under the fork crown, and if present, give the fork some air with a shock pump. I'd say the better part of 75% of bikes pass that treat with a working, if not well-functioning, headshock.
Before you pump it up, remove the schrader valve core and drip a little oil into the shock. The oil provides the final seal, and the shock will lose air quickly without occasional renewal of the oil. And a floor pump with a schrader head works fine.
I have a '93 mountain bike with a head shock. It only gets occasional use, but it still works fine. I did replace the bearings once.
