I have a 2010 Giant Rapid 1 and love it--I rode it to work today. It is a flat bar road bike with a carbon fork and seat post.

It's quick/sporty/fun. I feel more comfortable with my hands next to the shifters and brakes, so I like this style bike, plus the riding position is what I want. I tried a dozen drop bar bikes and went a good 5 miles on two different styles, but always felt uncomfortable holding my head up with the drop bar position, unless I was in the highest position. IMO, the design of these bikes is backwards--I'd put the brakes and shifters on the horizontal tops, which is where I'd ride when I'm starting out or slowing down. I could see me moving my hands to the hoods or drops when I get up to speed.

But, I don't mean to deflect attention from your post. Final advise: The most important thing is to buy a bike that you will ride. Nothing worse than having a nice bike you don't enjoy riding.
