I have both the V1 and the Escort 8500 Blue, definitely go with the V1 IMO b/c I don't "feel" safe driving with the 8500 compared with the V1 because the beeps means nothing without telling you where it is, in addition the V1 has a better read out for signal strength and is easier to just glance at when you get get a hit. Also, you don't have to change from city/highway mode (I like to drive with the "ALL" function on the V1 where there is no filtering)
