Roland pnc 950 value?

Recently picked one of these up. I was able to get it up and running through parallel connection on my desktop and it worked perfectly but I couldn't get it to run through usb on my laptop. Plus I don't think Roland is my cup of tea. (I'll stick with summa) Question is .. what is this thing worth? I'm thinking of putting it up for sale so someone can get some use out of it.

Desktop model,fairly clean, new blade, no stand but I do have the media holder for it.

 

Here is a picture of it.
