In preparation for my 2nd road trip across the US for Christmas vacation, from TX to KY to NY to VA back to TX, I've been contemplating a radar detector. Just got my GPS unit (TomTom ONE XL) so I know HOW to get there now I'm worried how many speeding tix to get there! I know the Valentine One is pretty popular but I'm leaning towards the Escort Passport 8500 X50, seems to have better all-around reviews. What do you guys think? What are you all running who have them?
