Hello, I'm looking into getting a scanner. I was looking at the Pro 164 but it looks like the Pro 107 comes ready to go. Is that true or would the 164 be better? Or should I stay away from Radio Shack and go with like the Uniden 125AT? I live in an area with only analog police/fire activity, I was just thinking about getting a trunking scanner just in case, but I'm not sure its necessary. Thank you.
