Ooooh man, that Bottechia looks sweet!

It looks very Italian in every respect. The red and white is a gorgeous combination, not to mention I'm a fan of gumwalls to and the 105, while a step below the 600, is still a good set-up. To bad neither are Campy's, but both have a good Shimano. The seat on the Bottechia also looks like a San Marco, which in itself is expensive. The color on that Colnago is just not doing it for me, and neither are the blackwalls.

I'd be leaning towards the Bottechia myself....
