We have used Cobra walkie talkies for years. Think they're about $50 a pair. Had 3 sets (6 handsets). Not sure we ever tested them to the 25mi quoted radius, but we've been over 10mi of northwest ks "hill country" apart and had no problem with them. Only complaint I ever had with them was that there was a "page" button or something on the front, so if you faced it out instead of in, it would "bleblebleep" on the other radios if you bumped it wrong.
