Best Radar Detector 2024 Under $300 300 Reddit. We ranked radar detectors based on our personal experience with valentine one and escort detectors along with thorough testing by dedicated radar detector reviewers. If you’re looking for maximum range at a more affordable price point, get the r3.

I don’t have one but i plan on picking up one on black friday to replace my aging r1. Originally the r3 was $400, but now it can regularly be found under $300 and now that it’s only a few bucks more than the dfr9, between the two detectors, the r3 is definitely.
