I've been thinking about upgrading my detector. I was thinking about getting an escort 9500, a Bel STI or a V1.(I've also been considering the Pro 78 Rev C.) At first I was sure that I'd get the STI because I heard that it's a great all around detector. But then I heard that the detection can become worse over time in the Ka band. So then I decided on the V1(Significantly cheaper.). The arrows were a big plus to me too. Then I heard that the newer units have a problem in the heat? Well, I live in Pensacola, FL. That's a problem. Is there anything I should know about with the Escort 9500i? Should I still consider the other two detectors? I'm trying to figure out what I'm going to get the best value in. I don't want a war between all the fanboys, I just want some input.
