I think someone had been trying to sell this for a long time, and at this point it has been for over one year. I first contacted the seller in August 2022 after the price had been dropped a few times. But I had first seen it several months prior. Anyway, the listing disappeared for several months so I thought it might have sold. Now the listing has reappeared again with the price about the same, $470. I think it had started at $800, then $650. Then $500, and at some point it got down to $480. Then disappeared for months, now re-appeared at $470.
I will contact the seller again, offer $400. She will probably counter at $465.
