Reply to Midi controller help!!

Im planning on getting a new controller soon, I believe i've decided on the 4trak. However, I would like something else to access the remix decks in traktor and for finger drumming, etc, on the fly. I have been looking at midi's like the electrix tweaker, the ohm64, the quneo, controllers along this line. I just wanted to see if what the best option would be for an addition to the 4trak. thanks!
