Cover for original H20

Hi,

I am in search of a new cover for my H20 (original). I have had the Kobo sleep cover since I bought the device, and it has begun to fall apart.

I don't want to get the same cover again, as it's rather expensive for what it is (and seems not to be easily available either).

Any body with ideas/recommendation, I'd be happy to hear about them.

Cheers.

Nik
