Go carbon fibre and get the same one I got off a lovely Italian chappie for 1euro + P&P (thanks to an error on his ebay listing). IMHO much better looking than the original and nearly as effective plus you can change the angle easier to suit your ride/head height.
No longer very naked my bike though
