I just recently bought a full carbon bicycle after my steel ride was destroyed in an accident. (Nothing like getting hit by a car that ran a red light to brighten your day!)
I ended up going with a Cannondale Synapse 1. The frame was stiff, light and very pleasing to the eye in naked carbon with black on black decals (I think Cannondale calls the color BBQ.)
The geometry allows for a more upright position in the drops and is a good fit for riding longer distances. It helps that the majority of my courses take me through the mountains so the stiff and rather light frame suit my riding very well. I got the entire bike on sale as it is a 2006 model so I paid a bit over 4k for a full bike with Dura Ace components and the Carbon Si cranks which are made by FSA for Cannondale. I sprung for some new pedals (Look Carbon Keo w/CroMo axles) since I felt my old quill pedals with clips and straps would look funny on this bike.
It amzed me how light and stiff the frame was. I have been riding steel for a while and didn't really consider carbon until I tried a few out and found them to be within my price range.
The best thing to do is go to the shop and take a test ride to see if it is worth it for you to invest the extra cash in carbon. I found that given the price range of bikes I was looking at the frame material was irrelevant with respect to the price and that component levels became the determining factor. At the 5k price point you can get Al, Steel, Carbon, Ti or any mixture in between. Going from Ultegra to Dura Ace affected the cost more than the frame material. I would have liked to get a Campagnolo build on the Synapse, but I've ridden both DA and Record and either one is fine by me. I'm not a pro, I ride for exercise and enjoyment and if I have the extra bucks to spend for the looks I figure, why not.
Besides after being almost killed by a negligent driver I felt that since you only live once, might as well spend the extra cash on some trick components. The wife gave me her blessing to budget up to 5k for a new ride, so I tired to get the most bang for the buck and still splurge a bit. 105 level stuff is fine for me, but since I could afford the fancy looking DA, why not?
I hope I'm still riding into my seventies gfp1931! Congratulations on your new bicycle purchase and I hope you have many safe and fun miles on it![img]cyclingforums.comsmile.gifOpen ↗[/img]
