The Valentine One is the KING hands down..I love wheeling as much as I love fast sports cars, so I definately have been through the ringer on this one. I have personally tried the Escort, the passport/8500, etc--NOTHING COMES CLOSE TO THE v1!!!. It's kinda like comparing our Landcruisers to a Kia Sorento, or GMC Jimmy.
The V1 has it's downsides, like it's BIG, and ugly looking, and difficult to hide (even with the remote mount, because the main unit still has to be in view for it to work)..(especially in a sports car)..in a landcruiser it's not so bad.
If you want THE BEST protection, get a V1 AND a K40 laser diffuser--THAT will give you time to react when required.. There are also some very trick setups that aftermarket guys have done to relocate the "bogey counter" to places like the rearview mirror (for Porsches /BMW/Mercedes, etc) or headsup display in the dash with mirrors to flip the display right side up and project onto a corner of the windshield.
Take it from someone who has taken his lumps with Garbadge radar detectors--you get what you pay for, and the only thing some crap job uniden/escort is going to give you is a false sense of security (no offense to those that own them--I used to own these also) Once try a V1 you wil NEVER go back.
