I recently rehab'd my 2006 Trek FX 7.3 for about $120. Not top-of-the-line parts, but its going to be my new errand bike. The BB and fork bearings looked OK, so I just replaced the cassette, chain, brake levers & calipers, cables, and large ring on front (ditched the FD, since I never really used it). Also added some larger tires (38's) although the older ones still had some miles on them (another $40). Runs nice!
