For a complete bike in that price range your best bet is probably used. Nashbar sells an entry level bike for $599 and this bike goes on sale frequently (sometimes marked down 20%). My Scattante Cross bike from Performance is an entry level model that I purchased 2.5 years ago and has served me very well. Nashbar and Performance generally use the same frames as they are owned by the same company. My frame was actually made by Fuji for Performance. The Nashbar Cross Frame( http://www.nashbar.com/bikes/Product...97_-1___202389) is pretty popular around here and is similar to my frame.
