I'm getting an iPad 4 for Christmas and I want to get a cover or case for it. I see the used smart covers go pretty cheap on eBay but I also see that monoprice makes some nice and simple covers too. I don't want to spend more than $30 or so on a case or cover so if you know of any standout recommendations, please pass them along. I don't want something too crazy looking and I don't need a hand strap on it, it also doesn't need to serve any other function except for protecting the iPad, or it's screen if I get a Smart Cover. Thoughts?
