I am interested in radio scanning and was wondering what is a good budget scanner to get started with that would work in Vegas. I am interested in listening to Las Vegas Metro and Henderson police department frequencies. I have no idea if I need a analog, digital, or a radio with trunking. I have seen a Pro 97 and Pro 94 at the local Radio Shacks that are going out of business. I think the 97 was going for about $160 and the 94 for about $120. I also don't mind looking for an older used RS or Uniden model if that would be better for a beginner. Any input would be appreciated, thanks.
