Since, I don't have a need or can I use a radio on 700/800 MHz, and I am not a HAM dude and never will be, and I don't intend to use MURS for anything, I don't think I would ever have a need for a multi-band APX radio. I thought about getting a single band APX radio for UHF just so I can learn about that series a little more but, I just haven't done that yet, maybe on a rainy day when I am bored and want to spend some money for the hell of it.
Since, I've had my GMRS license(s) since the early 90s, I guess I am one of those GMRS old dogs and UHF suits me fine.
