How much is the 1600 going for? MSRP appears to be $1319.99, but people have also been reporting deals on the 1500, some with Ultegra cranks/other pieces. It looks like a $120 difference between MSRPs, which buy you a 10-speed setup and an Ultegra RD according to the specs.

It also looks like the two bikes have the same wheelsets and paintjobs. I wonder if we'll see the return of the 1200 for 2008 models with the new Tiagra components.
