I recommend the UV-5R simply because it really does work and if someone isn't sure they will stick with the hobby, or money is tight, they are out very little. And, unlike many of the more expensive radios, you can put the walkie-talkie frequencies (FRS, GMRS) in it and use it just like a Wal-Mart radio (though technically it isn't legal to transmit on those frequencies) with it because it has too much power and a detachable antenna.
I have a UV-5R as a "disposable" back-up to my FT-60. It functions perfectly and the battery lasts a very long time.
