You can't really go wrong with a Yeasu product. I have the
VX-6R HT unit in my pocket, and the
FT-8800R in the truck. The 8800 is discontinued, but the
FT-8900R is basically the same thing, but a quad band. It's really 2 radios in one unit, has the detachable face, and cross band repeater function. The 8900 is also about half the price of the 400XDR. So if you're really into HAM or need the color screen, go for it, but that might be too much radio if you're just getting into the hobby.
You'll also want to get the data cable to program the channels, repeaters, PL tones, etc into the radio. But it's only convenient if you have a laptop to take with you into the vehicle after you enter everything into the software. It can be a little finicky but totally worth it. Or, if your friends already programmed their radios and you want the same memory set, you can download the memory from their radio to your laptop, and then just upload the file to your radio. That's what I did with mine.
*edit* You may only be able to copy the file from the radio and upload to yours if it's the same model...
