One more item to add to Don's excellent comment. As someone who prefers to build equipment rather than get it preassembled, the K2 is available as a you-build-it kit. The K3 and KX3 are only available as you-assemble-it kits.
I spent a year and a half dithering between the K2 and the K3 thinking, "Better radio vs. building it." I ended up with the K3 and am quite happy, but I still hear the K2's siren song. (And I will probably get a KX3 for portability before the K2, so go figure.)
