I ordered this one on eBay
The color ones look like the exact same one as the one I have in black now, with the cutout for the Kindle logo, but the black one pictured here also covers this logo, as far as I can see.
I've ordered it because my current one has a dirty spot on the inside of the flap. I probably put it onto the table with the flap folded backward while the table wasn't entirely clean.
The reseller where I got my current case is not on eBay anymore.
