For what you are looking for, I like the Midland GXT 1000’s. They are GMRS radios, but only because of the power output. The antennas are not removable, so one thing less for kids to play with. Not repeater capable which makes the radios less complicated.
I have two. The power output on mine is 3.8 watts using the supplied rechargeable batteries, which you and I both don’t like. These batteries are the equivalent of 3 AA batteries. However, you can use alkaline batteries without buying an adapter. When you remove the rechargeable battery pack , you will see receptacles for 4 AA alkaline. This increase in batteries gives my radios a power boost: one to 4.8 watts and the other to 5.1 watts.
At about $90 for two, I think you might like them.
By the way, I have been a ham for over 40 years, but a GMRS op for only just over 1 year. So, although I know radios really well, GMRS is fairly new to me and I can’t comment on other radios for you.
welcome to the clus!
