Well, the guy asked about radar detection suggestions, so instead of telling him all the ways to avoid speeding tickets (most to all of us speed, whether its 3mph over to 20mph over), I'll give a suggestion.
Many people already mentioned it, but it is by far the best radar detector on the market: V1. I saw a video of the Escort 9500i that supposedly is able to block out false signals and hone in on radar / lazers. The video showed it blocking out the false signal, but also blocked out a radar gun that was a little further down the road. Also, the arrows of the V1 are invaluable, at least in my opinion. I've had the V1 for quite a while, and it has saved me multiple times, so to me it is well worth the money.
