Thinking of getting a cheap backup vhf for the boat. Don't need tons of features, just need it to have average range and work when I need it. I'd like to spend less than $100. I find a few on eBay and elsewhere including this Cobra mrhh125 for about $50. http://www.overtons.com/modperl/pro...aVFl3nX3jaEmNTr2u-7fFdEGYZzo_CnGvYaAhNJ8P8HAQ This uses AAA batteries which is nice for a disposable since I can replace them cheaply. Has anyone had success with this unit or have other advice? Thanks.
