There's a guy on Craigslist selling his new 2012 Marinoni Delta with a Campy setup for $1500 obo. That's worth checking out because they are $1950 new plus tax.
For people who move from 105 to Ultegra/Dura-Ace,
most cannot feel the difference. Until you race, the upgrades will matter, especially when it comes down to weight savings.
But yeah, Cannondale CAAD10.
