A 2007 Ridley with 9-speed 105 components doesn't add up. I believe that the 10-speed 105 group was introduced in 2006. Something sounds fishy there.
Anyway, there were some pretty big technology improvements between the 5500 105 components (9-speed) and the 5600 105 components (10-speed). I don't think the extra gear makes a big difference, but I'm not sure a 9-speed 105 setup is better than a new bike with Tiagra components. For instance, what's the crankset on the Ridley? Does it use an Octalink bottom bracket or external bearings?
If you're willing to buy from Performance Bike, you can get a 2009 Fuji Cross Comp with 10-speed 105 stuff for about $1000.
