RE: Whats A good Radar detector Under $150
I have used my Dad's old one that he used to have in his M Roadster. At the time is was really nice, and expensive too. Driving around town I would know they were coming before they saw me. And RARELY it would go off before the police were in sight on the highway, they have Lidar anyways, once the detector freaks out they already have you speeding.
Unless your willing to drop several grand on one where they will pay for your ticket if you get one, dont bother.
