i am not in the market for a new (new used) bike. I have replaced parts, so it's definitely a better bike now than it was. Part of my thinking is also that I need a bike that is not nice enough to attract the eyes of thieves. I have been looking at the GF Utopia, but that would keep me worried when I lock it up somewhere. So yeah, I am quite attached to the bike I have right now.
Thanks so much for all the helpful advice, I learned quite a bit.
