Right now the '08's are rolling in and I'm seeing discounts--some big--on the '07's. Some of the bikes have the same frame, just different/better components for the '08's.

Some bike shops will take your bike as a trade in for a newer model and you can save some $$$ on your purchase. Is that an option at your LBS?

Good luck and let us know what you decide on. The Madone is a very nice bike.
