Likely forever. I’ve tossed a few bids at it, but this feels destined for about $2000. Also, this seller has less than stellar feedback, and been called out for bad packing. I’d pick this one up in person, he’s about 15 mins from me, but others... buyer beware, or ask for better shipping.That $300 one is now crossing $800.
I think it's safe to say Seas and SSE will be $1000+ posters for a while.
