Anybody into police scanners? I was at the local Radio Shack and there was one on display. Some of what I heard was pretty interesting. I figured I could use one to monitor what's going on in my neighborhood especially since I live two houses down from a park and this is the time of year that stuff goes on after hours there. I'll probably be hitting ebay for some deals since I'm not looking for a top of the line model. I'm wanting a handheld model since it'll primarily be used within city limits so reception shouldn't be a problem. Any suggestions of what to go with and what to stay away from?
