I never really use it anymore, so have decided to get rid of it if anyone is interested.
I have owned it since new.
It has a few knob covers missing (can be obtained from Novation probably free of charge), and one of the outputs needs attention (highly likely it's a dry solder joint).
It works perfectly, and is cosmetically in very good condition otherwise.
Details about the synth here:

The details of each model are a bit confusing on that link - It has a 32 voice poly, and 1024 patch memory.
I'm open to offers if anyone is interested. I'm currently based in the US, will ship worldwide.
