I have had the worst runaround with radar detectors as of late. I first started off with a Beltronics Express 925 for a couple of months, then I decided to upgrade to a Whistler 1743. For my birthday my uncle got me a $200 gift certificate for Flying J(intended for gas). I looked at the radar section, and instead of gas decided on a Beltronics Vector 955 for $280. After about two weeks, I was at our Flying J again and saw a new model, the Escort 8500 X50 for $299, so I immediattly returned the 955 and paid 20 bucks more for an 8500. It isnt too bad, in the end I paid 100 dollars for one of the top tier radar detectors.
Once I mounted the detector for the maiden ride, I switched it to Expertmode, I'm lucky I did because right by a construction update sign(A "K" false alert), I got a readout for two "Ka" sources and the "K". There were two Ohio Troopers running a construction speed trap. After about five minutes I knew I made the right choice in the 8500.
