Need an iPad Air Smart Cover that ISN'T from Apple.

Hey guys, I've been searching around for a Smart Cover, but the one Apple has is too expensive for polyurethane. If I'm gonna spend that much on a cover I'd like it to at least be leather. Was just wondering if any of you guys have seen any Smart Cover substitutes out there. And I don't mean something with a back case on it, I literally just want the Smart Cover that attaches magnetically lol.
