I went on escorts website today to check out the new Redline (I'd really like to get one, they seem sahweet!) and I noticed they have a Tune-up program for your current detector. Since I'm on a college budget I'm sorta entertaining this idea vs getting the new redline. I have an 8500 X50 that I got off of ebay almost a year ago for about $170. It was in worse shape that I would have hoped, but it seems to work fine. Thoughts?
