First off, let me tell you that my first detector was an X50 (saved my ass so many times). Well, that got stolen so i ordered the original 8500 off ebay. I know this is an intro section, but i would just wanted to know if i would be disappointed by downgrading? I do the majority of my driving in the city, and i would like to drive with confidence i had with my X50 (you will be issed haha). Thanks everone, I'm hoping to learn a lot on this site!
