I'm looking for a good, affordable scanner for use in my automobiles. I'm looking to not spend over $100 total, though I can go a bit higher if need be. New,used, ebay is all fine. I have two cars and it would be great if I could easily switch it between the two. Decent range is ok, I don't need to listen to things from 20+ miles away. I like the idea of a uniden with beartracker warning, but I'm guessing it's not really that useful so it's OK if I don't get it. Thanks.
