Part of a compelx 5 hat deal deal for a Kill-a-Watt Viewfinder, would put it to ~1.3 anyways, ignoring any overpay calcs and outdated prices so consider it a bit of supporting evidence and nothing more

These actually sell pretty rarely, only sales since end of November it seems and even then that was the only one to sell since spring. Considering the multiple attempts at manipulation of the current owner before they even bought their current one (look at the suggestion history of this hat and the date of the first sale) of this one I'm going to take a wild guess that they won't be selling it anytime soon either.
