Which DJ controller should I buy ?

I am a mobile DJ buying an entire mobile setup and i have been looking at 2 particular DJ MIDI Controllers. The Denon DN-MC6000 and the Numark NS6; I've been going crazy trying to decide and I need some opinions. I plan to mix video in the future and add the Serato Scratch SL3 with a couple of CDJ-2000s, but video isn't exactly crucial for me, so it's either or.
