It took me a couple of months, but I finally found mine on KLOV and even then it's noticeably used.
I really wish there was someone who reproduced MVS art (CPOs, marquees, side art and memory stick/headphone decal). And I mean the original plexi material for the CPO and memory stick/headphone decal, not vinyl. It seems there are a lot of people who are unable to fully restore their machines as most art out there is heavily used or non-existent.
I know someone who paid close to $100 for a NOS CPO. I'd say a used one in fair condition is about your asking price of $35-40 which is how much I paid for mine.
Good luck in your search.
