So I just ordered mine from Ebay for 14$, the "CY Magnetic Ultra Slim Folding Cover Stand Leather Case For KOBO ARUA H2O 6.8" . Hoping there isn't really an ARUA model being sold somewhere in Asia

Gecko has a similar model, from what I can see it's based on the same plastic shell, but probably the faux leather and the craftsmanship are of better quality, and it costs 30$. However my Aura 6' cover, which I also got from Ebay, and which looks exactly like the one I have just ordered for the H2O (only smaller) is perfectly ok after some ten months of carrying in my backpack and it looks more expensive than it actually is.

EDIT
Actually now that I'm taking a better look at the pics, the material of which the Gecko is made looks identical to that of my Ebay "original"
