i've had the bel v940 for about a year and i love it. Saved me more times than i can count. Was looking to buy a new RD for the wifes car. Read some good stuff about the whistler xtr-690 and it has a few features that i like that the 940 doesnt have but i dont want to give up the performance of the 940. Does anyone know if the whistler has the same range as the 940? Also what about Ka detection and laser performance? I'm looking in the under $200 price range.
