Swap my 4P card for your Polivoks Card?

Hi, was hoping to get hold of a second Polivoks card and was wondering if anyone here would be interested in a brand new 4P card? UK based would be preferable.

Just got the 4P card last week and after some messing about with the synth, I have decided I would rather have a duophonic Polivoks / 4 voice SMR4 poly synth set-up.
