I second BikenBen's post. Steephill.tv and cyclingfans.com will link to the various Justin.tv-rebroadcasts.. Cyclingfans has a twitter and facebook link if you want the lastest updates on new sites, and they update whenever a good link comes up. This way you can skip Phil and Paul doing the Lance-dance, and get Sean Kelly's laconic take on what's up on Eurosport UK or Laurent Jalabert's on Eurosport France. And Rai gives you Paulo Bettini on the back of a motorbike jamming a mic in people's faces.
And for some astute commentary, try Podiumcafe.com.
21 days of joy!
