Bel RX65. I am a happy owner of one and the range is incredible not to mention it is much cheaper than the Escorts.
It went off one day while I was doing 80 down long highway. A minute later, I see a cop on the opposite side of the road and I was like WHOA! We were at least 2 miles apart at that time. Laser detection is very good also. It warns you when there is laser in the area, not when you are directly hit (at least with the lasers in my area).
