Vertex Standard VXA-710:
The Good: Small size, good audio quality especially through the headset jack, great battery life including storage time, solid construction, very durable and advertised as submersible.

The Bad: I have real trouble with the buttonology of this radio, and I'm pretty much a tech guy. I need reading glasses in order to see the button function text above the keys, especially with some text in yellow on the silver background.
