I fly the DX6i and believe it to have plenty of features for how i fly. love it, man....Comes with the AR6200 but no servos.

I know they offer other DX7 combo configurations for those who need beefier servos and what not, but the one you have linked seems to be correct for the King 2...The DX7 is superior to the DX6i in a few areas. More settings, smaller, more ergonomic feel, less plastic-ey feel to it(not toy-ish like DX6i), 1 more channel, doesn't have the all-in-one sucky roller/button....There are other differences comparing them to the DX6i but price of the DX7 is what freaked me out. The DX6i works on the same exact DSM2 as the 7. I believe you get what you pay for with either of these 2 radios. If you are ever going to fly nitro, you need the DX7.

Then there are the Futaba's with the fasst 2.4 system and the grand daddy of the Spektrum, the JR's. Your choice. They will all work with the King...Yes, this list does not even scratch the surface on which radios work with the King. Pretty much all of 'em do. How much you want to spend is the key.

Good Luck
