I've been interested in radar detectors and their technology since I got my permit. Right now I have a crappy cobra ESD 7000 and am unsure what I should get for a REAL detector. I'm 17 and don't have a job so I don't have a very high budget. I heard the Whistler Pro 78 is the cheapest quality detector you're gonna get but I was wondering if anybody had any recommendations that are possibly cheaper that they have found to work. Thank you!
