Was about to the post the same thing but ya beat me tooooo it
Looks like a details/spec mess up, willing to put money on the fact you get whats listed in the title, which is the H55, which you can get for under $50.
If that was the original page, it doesn't load for me, probably taken down. People were probably ordering 20+ at a time and threw a flag to someone running their ebay page.
The Google shopping page lists it for the same price on ebay, but you click on the link and it says the page doesn't exist, just like the second link here.
That page does come up for me.This link is what I originally posted, it says h100i v2
but you're probably right.
