The CAAD8 is a fine frame, and probably the best "budget" frame out there. Cannondale is sort of unique in the way they "trickle down" their designs. A few years ago the CAAD8 was sold as their top-of-the-line orad bike with DA components, etc.. It's a great, great frame for the money.
I recently picked one up too while my main bike is on the disabled list, although mine isn't exactly stock.
