I got the Kobo one but I don't like it.
I am now using one I got from China through Amazon. Not sure if they will ship to your country. Here is the Amazon link. I have to say that mine is defective, though. You'd get a better quality cover, I think, from Gecko in the UK. I much prefer the design of these two covers. There is an 8.99 cover thread here in this forum that shows another option. I have that one too but I prefer the slim style.
Shoot. I was thinking of the Glo. For the Mini, I also got the Kobo cover and don't like it, and have been unable to get a slim fit cover. I am using the 8.99 cover from China, and I also have a Navitech that I got for $5.00 from Amazon. The China cover did not have the sleep function but I added a tiny magnet and now it does. So if find a cover you like, you might be able to add a magnet.
