I gotta say that I love my Steamroller, but the argument for the water bottle bosses on the Paddywagon is a good one. They're also pretty reasonably priced, easy to find, and as far as I've seen they basically look like they're built like a steamroller but with extra mounting points for fenders (training in the rain) and racks (good for commuting, and commuting = base miles baby). I've also never really known the difference between 4130 and Dedacci (no idea how to spell that) tubing so I'm afraid I can't factor that one in. Lemond Fremont might be another good one to check out.
