MX-3's RULLLEEEE!!! I've tried about 7-8 radios, and the MX-3 was by far the best. I liked it better then all the JR radios I've tried (xr2, xr3, xs3). And all the other misc radios. The MX-3 has a PERFECT feel to it. I wouldnt trade it for anything else (unless it was like a M8 or something). The functions are soooo easy to use also! On the screen it lists all the functions, and when you turn the radio on, the function you are on lights up. This way, you can toggle through the fuctions you dont want and find the one you DO want as fast as you can click the button. I highly recommending this radio, and have been running it for about 2 years.
On my brothers 3pm, there is NO indication of where you are with the functions. You have to watch, and go slow or you'll miss your function. there is NO BACK BUTTON, It costs more, the functions are impossible to see on the screen, and they pack in the abbreviations so close together that you can't even understand what they are unless you've seen it before (ie, EPA, TRIM, etc). I really hate that radio.
