Craigslist has been pretty much useless for me as well. Every time I see a bike on there, it's either a nice bike and overpriced (like a used and not rare Trek 520 for $1200), or it's way more bike than I want (some carbon thing for $1500, probably a good deal, if I wanted a carbon bike), or it's crap and overpriced, like a wal-mart bike that sells new for $120 for $110. That sort of thing.
