Just my .02 on this topic. I bought a lightly used 2005 OCRC3 last spring and promptly put almost 3000 miles on it since the beginning of May. Granted, it's my first road bike, but I did test ride a small number of other frames before finding this on Craigslist. I paid $900 and thought it was a pretty good deal. I've left the drivetrain alone, but have upgraded, seatpost, seat, handlebars, and put some look pedals on. This year is probably going to see an upgrade in wheels. I'm excited to see what the bike will do with different wheels.
