I believe there's really no dispute that the V1 has been one of the top choices for a number of years. I'd love to have the arrows and from what I've seen it's sensitivity, at least for most straight-on situations, is amazing. It would be great if one radar detector had all the bells and whistles, but of course patents won't allow that. The Bel 9500 allows you to mark known locations by GPS for falses from door openers and such so you aren't bothered repeatedly, the Bel STI offers absolute stealth against even the latest radar-detector-detectors, the Escort 8500 X50 displays up to 8 different simultaneous threats.
There's precious little you can do to avoid instant-on radar, but if someone is really serious about LIDAR (LASER) traps there are options for passive and active counter-measures. There's Veil coating for headlights and license plates and at least one or two other covers for plates. For people interested in slightly more aggressive measures, I know there's the Blinder LIDAR jammers. Keep in mind that LIDAR is not actually LASER, it's infrared light. The beam is tight, but from what I've heard at 1000' the beam is about 3' wide. For anymore with more interest in good reasons why to take precautions against LIDAR, search on problems with "slip effect" or "panning error" and how the guns can return false readings.
