I just saw those(Full Metal Fenders) on a bike in the window of one of the local shops. Thought they were pretty cool...until I saw the price!

Won't commute on a bike without fenders,won't even go out in the rain without full fenders either. First time in the rain I got filthy. Tried a set of clip-on fenders,not much of a difference. Got a proper set of full fenders and the dif was night and day.
