MOTM

I am looking for a non-MIDI non-keyboard, non-Theremin controller for
my infant modular.  (I have my eyes set on the MOTM MIDI-CV device but
it is not yet shipping and a cautionary angel on my right shoulder is
telling me to let it ship for six months before ordering one.  This
angel is conservative I guess.)

So in the meantime, what controllers would people point me in the
direction of?
