Rhodes Chroma Polaris

hi there chroma lovers/freaks,

now that i've got my polaris here in my new home,
i plugged it, everything is functioning well, i noticed
that i'm too old for making music again, and too much out of it
spin the knobs...
so, does anyone knows whats the actual price for selling a polaris?
(i live in germany.)
does it got an oldtimer bonus??

greats
