Two-way radio

[cema]

Who would recommend me how to choose and buy one (or two)? I need it for things like camping, hiking (no heavy mountaineering, some light mountaineering maybe), caravan driving (to get around town or between towns in a party of two or more cars), cross-campus talk (to save the cell phone battery).

Unlike digital cameras, the online reviews I have found for these have been suspicious and/or incomplete. I hope you could give me a better hint.

Thanks in advance.
