I have found Colnagos, Treks, Raleigh Internationals and Competitions, Bertins, Atalas, etc at yard sales. Never paid more than $100 for any of them. Pretty much luck of the draw, but it helps if you are in a larger, "Bikey" area, you are not going to find this stuff out in small towns in Appalachia, for instance (which is where I am now). The best find I ever ran into was a yard sale ad that said "road bike parts". Went over there and found a guy who had been the manager of one of the pro womens teams back in the 80/90's (7-11 I believe), and he had a bunch of their old stuff!!! What a motherload! Wheels, hubs, cranks, derailler, handlebars etc etc. Of course I had to be picky and just took what I thought I could afford at the time, should have grabbed it all!
