I bought a KX3 as a reward for completing a very difficult certification. I earned that $2500 radio, but dang if I'm not scared to actually take it anywhere because it feels so fragile for how expensive it is. I included the battery compartment when kitting it out, but ended up removing the batteries and relying on an external LiFPO battery because I didn't like cracking the radio open like a clam every time I needed to change them.
Something like this would make a whole lot more sense for my QRP needs. It's far, far cheaper and looks a bit more sturdy.
