[Elecraft] K2 remote antenna tuner question

[R Thompson]

I'm shopping for a remote antenna tuner that will work well with my
K2/10.  At the moment I'm favouring the LDG Z11ProII and building a
weather proof container to put it in. The LDG draws little current and
may be battery powered.  SGC make outdoor tuners and they have a wide
temperature operating range, down to -35C.  However they need external
power.

Customer service is important to me, as is reliability.

Recommendations?
