Gah I only read like 1/3 of this thread, but anyways... the two radar detectors you will choose between.
Passport Escort 8500 X50 or the Valentine One.
The Val 1 is $100 more at MSRP, but it does have high performance and has the arrows to tell you where the radar is coming from. For example: You are crusing down the interstate and radar hits you. You would think it is from the front, but there are cops that do go 10+ over the speed limit (it is illegal, but who is going to stop the cop???). After like 10-20 seconds you think it is safe again to start speeding up as if the cop was on the other side he would've went passed. But he is really behind you and that is where the Valentine One comes in handy.
Escort 8500 X50 has better POP detection and perhaps exceeds/matches the performance of the Val 1 except in laser. You can choose between red or blue as the LED color. There are many review sites out there that are pretty biased, for example: Escort 8500 X50 receives a 99 where the Val 1 gets a moderate 80. The difference between the two isn't that big at all.
Just a FYI, if you get hit by laser you can't brake in time to lower your speed. Also, laser is more focused so you probably won't pick up the laser signal unless it hits YOU.
Bottom line: Both of these radar detecters are top of the line, but the major difference is the Valentine One has directional arrows and probably a tad bit less in performance overall when compared to the Escort 8500 X50.
I own the regular Escort 8500 and it is pretty good, but I would love the arrows and sensitivity of the Valentine One combined with the performance of the Escort 8500 X50. 🙂
Edited for numerous grammer errors. I never get it right on the first try. Probably some left, but you guys get the point! 😀
