I'm finding that the Surly Cross Check is a great urban commuter. Tougher than most straight-ahead road bikes, so I don't worry about potholes or, for that matter, curbs; the drop bars are comfortable and let me get out of the wind when I need to; and the relatively short wheelbase makes it extremely agile in traffic. Steel frame feels supple without sacrificing much in efficiency.

I'd think about a cross bike if you're bombing around urban areas, though these vintage touring/road bikes are sounding pretty great...
