According to the "official TDF guide", most TDF teams have a 2006 budget of around AUS$10 - $12 million. Notable exception is T-Mobile on $25mil, but then you have at the other end of the scale Agritubel at $6m.
Not bad value, given a typical cycling team has 25 to 30 riders on their roster plus support staff.
Compare that with a typical V8 Supercar team which has an annual budget of around $12mill, and that's just for 2 cars on the track.
If we all check under the couch for loose change, we could easily get a team together.
