Left-handed theremins?

I've been looking at instruments out there for purchase, but they all seem to be irrevocably set up to be played by right-handers.

Do you know of any that are pre-built that have the option for vertical antenna on the left?

Moog Claravox has a left handed model if still available.

It probably doesn't help you, but on the D-Lev this is just a matter of setting the PV knob to 3 (in the digital world much of this kind of thing is fairly trivial).

While on the subscope models with knobs on top you just play it from the opposite side (in the analog world we don't even have to dive into settings :-).
