Currently using the 9500ix and the ZR4 shifter. The detector has paid for itself literally countless times over, especially considering the GPS function for speed cameras which are everywhere here. The only good thing is that because of the speed cams generating so much revenue, there are rarely any actual cops out doing speed traps
And radar detectors, laser jammers and all the like are totally legal out here in the 'Wild West' lol.
The ZR4 has been good so far, haven't had any massive saves from it on the HWY yet, but it's bought me some time in the city before.
