Speeding Ticket

I recieved a speeding ticket yesterday (63mph in a 45 mph zone). Has anyone successfully fought a speeding ticket and won even if they were totally guilty? I see all of these "fight your speeding ticket and win" websites for $20-$30 and was wondering if they are a scam or if they really work? Am I better off going to traffic school to keep it off my record? I was ticketed in Cook County (Chicago and some surrounding suberbs), high noon, clear day, straight road, very little traffic, radar gun. High power lines run right next to the road that I was traveling, would this interfere with the radar gun? :cussing:
