Don't pursue too hard then as they are likely to use whatever your offer is to get other people to try to pay more.
I'm the only person who has asked anything about it so far, but I pretty much just made some banter about appreciating CRTs as much as they do and for them to get in touch if they ever decide to sell it for around $200. Who knows, I could get a message in a few weeks time, but I won't get my hopes up.
