Has anybody on here used or own one of these rader detectors? I was driving a guys truck and trailer on a trip that had one of these in it and I must say it works very well (I was impressed) detected some cruisers at amazingly far distances. I have never owned a radar detector before, but used some cheap ones. If the thing wasn't 500 dollars I'd probably get one. I figure it's probably cheaper to just "not speed". Just wondered if anyone had used one?
