I just received an el cheapo (~$10 delivered) ebay Hong Kong K4nt black cover in the mail today (took 3 weeks to get here btw). I was not really expecting too much. Tell you what, this thing is great!
Fits like a glove and the black inner-border does help improve the K4nt contrast a bit. One very small complaint is that I found I needed to push a little harder on the down 5-way because the cover comes pretty close to it (and I have pretty fat fingers, lol!)
The magnetic clasp works fine and when you fold it back to read you can attach it to the back to help hold it open. Gives you a nice little gap for a clipon book light as well.
This is a keeper!
For USA guys I think you need to look at this ebay ad;

For Ozzies, this is the one I actually bought (does not ship to the US) and you can save ~$0.50;
