Was thinking about getting one of these things...

There seems to be a lot of these on the market out there with a huge
range in prices. Among the cheapest ones I found was the Humminbird VHF
Radio for $60, but they can apparently cost as much as several hundred
dollars.

So, how much does price matter? Do you really need to spend more then
$60 to get something worthwhile? If you own one, which one did you
decide to get?
