Go read up on radar at www.valentine1.com It has tons of info on radar. My dad had a valentine one and that thing is awesome. Great radar detector. The best budget option if the bell 980, around 100 bucks iirc and is a great detector. I think the fine in VA for having one is 50 bucks and they take your detector. If you get the V1 you can buy a stealth thing for it that basically relocates the display so the actuall unit will be dark.
