I just bought this radar detector in hopes of avoiding any police interference in my quest to beating every Rice-Rocket in my town. I looked into the Valentine1, but I don't have $400 to spend on any kind of radar detectors, so I bought this Bell 870 instead. It is a very nice radar detector and the SWS system allready alerted me of a fire trucks in my area before I even saw the smoke! I have no other experence with other detectors, so what I have to say is shallow.
