Buy what fits him and is fun. Don't buy for components or frame. In my opinion, the frame and components hold back very few bicyclists. The only thing a common brand has to offer is a look and warranty. Practically, any bike in the $750 is going to be perfectly find for occasional use. You aren't going to wear out parts any time soon. You're looking at a $50 frame built in Asia. After your friend has spent time in the saddle and knows what he wants (provided he doesn't get bored), then be picky about frame and components.

Giant and Trek offer great bikes for the buck. You can't go wrong with either, as long as the fit is good.

Cam, I think you will really like the Roubaix. I'm in love with my TCR Composite. It fits me better, and ride is so nice.
