My friend has just brought a KO Helios about 5 months ago and i have felt it it is probably the most ergonomic radio i have ever picked up he also runs a lithium battery in it so it is SUPER LIGHT and the menu looks really easy i just got my 3pk about a year and a bit ago so i wont be buying anything new anytime soon but i quite like the 3PK i also run a lithium pack in it which makes it lighter but i think you get used to it after a while anyway

cheers
Chris
