If your're looking for a TREK FX 1 or 2, Craig's List seems to be the place. This is just anecdotal but I do seem to see a lot of FX2's for sale on the List. I think it is probably one of those starter bikes that people buy and then they either drop out or move onto another model. Don't be fooled by the prices on Craigs List either. I always see people thinking they can get a whole lot more than what the bike is worth used.
