I’d have to agree.
Even though I already own it by now, I’ve paid 1k USD for my copy three years ago, and if I would come across it for sale again, I’d happily pay 100+ USD to resell for a profit to other Pikachu collectors I know that are still looking for it…
I’m also still regularly looking for the even rarer version (Glossy Keiji Kinebuchi with shifted artwork), and I haven’t come across it nor this 2k limited version even once in the past three years, so it’s far from easy to find either.
But with how unrealistic some prices in my own WTB thread are, I can defintely understand just having a WTB thread regardless of the price just in case someone comes across this card. 
So best of luck in your search!
