Another idea for a Seattle bike - the Swobo Dixon; not a SS/FG, but a bit of style:

A revised version of an REI commuter. Zero style points, extremely practical for Seattle (internal hub, disc brakes, etc.).

Or, just get a 'cross bike (like the Redline Conquest or Kona Jake the Snake) and throw a rack on the back.
