if you don't like any of the aftermarket ones try the new ones fitted to 07 and after. Not gonna be as cheap as the aftermarket ones, but you may find someone who's got a pair on ebay or off here, or try a dealer....
I've got a pair that were on Echoance's bike. Love em. So subtle...much better than the Foreman Grills.
