I have the BTECH GMRS-V2 and I like it very much (for a CCR). It does CTCSS and DCS tones. It gets decent reception with the stock antenna. Slap on a 771G antenna and it gets pretty good reception. I give it to my kid to run around with. It gets left in damp fields overnight and dropped off of the bicycle and it keeps on ticking. I wish the belt clip were a little tougher, but it works. It is programmable with CHIRP and the ubiquitous Kenwood K-1 / USB programming cable. The battery lasts pretty good. I can hit all of the repeaters around me.
Skip the UV-5R. This would make an excellent first GMRS radio.
On my FARSOMETER 2000 (on GMRS channel 01) I get 4.04W on high and 1.26W on low.
On my frequency counter with a TCXO I see that my unit TX about 145Hz too high. I gotta get my SA set up so I can see these "spurious emissions".
EDIT:
I paid about $50 for my GMRS-V2. It has separate red and green RX/TX lights and the keyboard is backlit. Like on the UV-5R, the small letters/numbers on the screen (not the main ones) are hard to read because they are so small, but I'm old and my eyes aren't what they were.
EDIT EDIT:
Also, the battery is securely clipped in there, unlike on the UV-5R. I wish the battery contacts were gold plated, not just nickel plated, but they work just fine.
