I have read great reviews on the Valentine One, and I agree that it is the best that is currently available. However, I don't agree that it is the last you will ever buy. I have an interesting story regarding radar and radar detectors. When I was an undergraduate in Durham, NC, the inventor of the police radar spoke to us in one of our engineering classes. I don't remember his name, only that he was Korean-American (it was a long time ago). The interesting part is that he was the first person in North Carolina to receive a speeding ticket and be convicted by his own invention (he was rather tickled by that). The reason that I say the Valentine One will not be the last radar detector you ever buy is that the same manufactures who develop the radar detectors are the ones who are developing the radars. It's pretty much a self-perpetuating business.
