CAAD9 is the best frame at that price, but you'll have Tiagra (eww) until you upgrade... Otherwise its cheap carbon

I think last year CAAD9 with 105 was £999 but they increased the prices for the '10 models..

are you kidding? The CAAD9 is Aluminum.

The SRAM Boardman Team Groupset is better than Tiagra and the Aluminium version of that is £200 cheaper.

Cannondale is overpriced.
