4 deck controllers

I've noticed lately that the hardware developers are releasing more and more controllers with full 4 deck solution. It looks like the standard now is 4 faders and 2 jogs... Hopefully they will come with 4 jogs soon.
So what four deck controllers are currently on the market? Give me feedback if there are some controllers I've left out! Cheers!

Native Instruments Traktor S4

Native Instruments S4

Since it's engineered by Native Instruments and has a tailor made software this controller is naturaly in a different league then the other controllers.

This bad boy from Allen & Heath  is made for Serato Itch and has an awefull Itch sticker on it. On the bright side the button setup can also support a Traktor Pro Workflow and even the effects will be handled.

Just wanted to add this to this post since it is just so darn cute. :) It's got some buttons, but to be called a full blooded 4 deck controller would be taking it a bit to far. It's got four faders and if you got a controller on the side this would do for the mixing part. :) Love it!
