Major brand like Motorola, Cobra, Uniden, Midland.
I have always used Motorola.
Most all accept AA or AAA batteries.
All have about the same communication distance about 1/4 to 1/2 mile.
Some more expensive models may have weather channels.
I would go to a local big box store and see what they have in stock and compare to prices in Amazon.
Try and buy a package that has the accessories you want in the package.
Uniden has a submersible FRS radio that has rechargeable batteries/desk charger and ear bud/microphone that looks interesting for about $80 a pair.

You can get radios much cheaper or more expensive depending on accessories and features.
Most features are not used but can sometimes come in handy like NOAA weather alert, scanning, CTCSS and DCS (way to ignore other people on same channel), Roger beep and more.
Ignore the claims of distance. All will work about the same distance.
In the end all will work for 1/4 to 1/2 mile so buy what looks good to you.
