If you drive fast, get a radar/laser detector....i'm currently using my fathers (he shipped his car to europe) Passport X50, it works like a dream, i know where cops are even before a corner. I personally wouldn't get it cause it's a hefty 250 bones but i also have a whistler 1788. It comparible to the the regular passport series. If you goto
http://www.radartest.com, you can get reviews on radar detectors. Most expensive doesn't always mean best.
And ever since i got my ticket, 4 years ago, i've had a radar detector and they HAVE saved my a** a few times.
