I'm so glad to have gotten so much feedback on this, sorry I couldn't figure out how to post the pics on here and had to link. Robtown is sending me the plate I need for free so that's pretty cool. I just got a set of 27" alloy arayas and am trying to get my hands on a 600 group for a reasonable price. It'll probably end up replacing my 3 speed univega as my go-to bike for work. The guy at my LBS thought it might be a slightly up-market frame as the one he happened to have in the shop had much simpler lugging and even cruder brake mounts.
