Ok So I know that most have said ALOT about the Trek 4300 but my question is really a oppinon based question, I am going to purchase either a 4300 new, Haro V1 new or a little older Cannondale f400 but am not sure which would seem best. The LBS said that the cannondale frame alone would go for 900 but he would sell it to me for 500. Is that an acurate cost on the frame? Would the cannondale be a better frame to upgrade? Please advise cause Im tired of walking everywhere.
