Wireless keyboard suggestions?

For when I'm on the road during book tour, I'm looking to get a keyboard that I can use to type longer email messages and blog posts on my iPad2. The obvious choice would be Apple's own Wireless Keyboard, but I thought I'd throw it open to the hive-mind. Does anyone have any other suggestions for keyboards worth considering? (I already have an iPad cover that I really like, and the covers with built-in keyboards I've looked at haven't impressed me much, but it might be nice to have a keyboard with a stand the iPad can sit in while I'm typing.)
