I have a carbon fiber one arriving from Casoli within the next week. I'll let you know how it turns out and post a pic or two. Very reasonably priced here in the states, too. Well, reasonable when compared to the stock piece. I'm getting full carbon fiber painted to my specifications for less than the stock plastic item.
Looks very cheap @ £165. What exactly do you get for that? Is that painted? Does it include the seat unit (aren't the single-seat seats bigger than the bip ones?)? Presumably you have to transfer over the lights, catches, hinges etc.
