I'm in central WA state. I'll more than likely be doing this via Craigslist or visits to the LBS to see if they have older used bikes. The one in my town told me he has an older Trek with 27 in tires but has to remember who brought it in before selling it. I don't know a lot about the different models and would prefer one that isn't much heavier than the mid-20 lb range. I'm not real picky on the drive train or shifters but definitely would like downtube shifters - if not just for the nostalgia aspect. I do prefer something where parts won't be a big issue (i.e. available and not cost prohibitive).
