Sort of on topic: Droid Turbo 2's can be had refurbished for about $100 now. Even without a case they are one of the most durable phones I've ever had. Mostly waterproof, unbreakable screen, etc. I literally have dents in my screen, no biggie. They'd be a decent option for a rugged phone/radio combination. (and also have a 20mp camera and record 4k video)
