Not a road bike, and not exactly vintage, but I've got a 93/94 Univega Activa Trail for my commuter. 21 speed, cantilever braked hybrid. I love it - it's comfy, rather fast, can fit fenders and tubby tires, etc. The only problem with it though is that when the back is loaded over 25-30ish lbs, the frame feels pretty weak (wiggly over bumps, etc). Only done it twice though...
