Is it Worth this Much?

You are right. I thought this might have been a vintage, new, old stock item but I see they still list it on Brio's web site. Didn't know it is also motorized. Don't know if the seller is that far off with looking at the wide range of prices at Amazon. https://www.amazon.com/s/ref=nb_sb_noss?...tching+set

Perhaps it's rare in Japan?
I've seen Trackmaster Revolution engines go for hundreds a piece from Japanese sellers on eBay and Amazon. Looking at these listings, I always see something along the lines of "not available in Japan" or "ultra rare in Japan," so it's clear to me that they're looking to sell to someone living in Japan.
