Craigslist and EBAY are certainly your best sources, but if your screen name is any indicator of where you're at- there's a couple used bike places around our area you can try- Drum Hill in Nashua, Rick's in Plaistow, and SKY in Fitchburg, MA is a little further out. There's also one in Hookset, but the name escapes me.
Be advised that the used bike places I mentioned around here are way too **** overpriced for most of the stuff I've inquired about though.
