Trust me. Get a 5w, don't go half ass.... cos you will end up upgrading and wasting your money.
For those who wern't present
I picked my one off ebay, Uniden uh078sx 5watt, extra long battery time, spare battery, breakout box, and you can also get a car charger. Antenna can also be upgraded if you want to use a real serious antennae for your car.
You really need the range, road wise it helps heaps for cruises, long road trips. esp with lights/ traffic / twistys etc.
In the winterwonderland, its water proof, and again range, I get communication from Base to Peak, no problems, other smaller radios drop out half way down the mountain. Breakout box is a must cos its shiethouse when you have gloves, rummage thru your pockets and try to press the button, not to mention dropping the damm thing.. (yes its happened to lots of my friends) Just chuck it in your camel back and box on your shoulder strap.
Some cheaper radios also don't have the breakout box plug, they may have VOX, but they don't work very well. Plus I have my phone and ipod plugged into my lid.
The uniden is also built like a tank, Bonus, if you stack bad - yes i do that a lot.
There are repeaters can help extend range, but they arn't always around.
The Garmin GPS and friends option looks pretty niffty.
SUMMARY: ....
JUST DO ITTTTTTT - Don't skimp, Geta good one, cheap ones are Mickey Mouse.
Just like Cars, MORE POWA!!!!!
