My Trek 520(steel) made a great commuter. I've test ridden a Portland and came away with an impression that it would make a fine commuter. I've also test ridden the Jamis Aurora and liked it very much. If you really like a more comfortable steel hybrid, look for a used Trek 7XX series. Last summer I picked up a mint '96 720 for my daughter for just $50 and she loves it. Here is an older pic.
