This is the most popular French selling site. Even just getting the link for you theres a nice looking Gitane at 99€. I look at UK Ebay too, and another french site, and theres almost always something interesting on there. Whether or not I want to chase it is another matter, but I've had a UFO Vitus 999 frame at 20€, a Peugeot at 40€ (in another thread) and a pink Mercier at 20€ just last week...
