Hmm... the only price guide that's really frequently updated says 10k, but it's really been a while (probably weeks) since one has sold, so I think most sellers would take bids.

You're a bit lucky that there isn't really a high demand for it though. If you're looking for one, I suggest asking in Cazzidy's or Panda's selling threads. They tend to have older items available.
