I bought my R600 in '04, although I suspect that it was really an '03 (closer match to those components, although not much of a diff); I paid $999 for it. Assuming that your bike is in good shape (it's new, right?), I'd say it's a good deal (not killer) and that it is an excellent entry-level (or slightly above) model.

Major whines that I hear are the wheels (Gipiemme Tecno 024), and the brakes, although I have not had any problems in 2500 miles with mine. I'm quite very happy with mine after getting the fit dialed in, but like all roadies, I am curious to try others and compare (e.g., if I upgrade the wheels, will I fly up hills? I doubt it)
