Hey I have nothing against the 9k or 9 Pro, and wouldn't in any way talk bad about them.. I think both the 9k and 9 Pro are awsome keyboards... Hell I'd love to have either one of them, but taking care of my wife and my child come first.. That's why I have the 550.... It's easy on the pocket and for the price it still is the best bang for the buck.
