Reply to Best traktor controller 2014

I know there are other posts about this in the past. But i am just curious as to what people believe is now the best controller for traktor. I feel the s4mk2 has a huge amount of issues, and honestly see no worthy improvements over the s4 mk1. Maybe if it actuallly worked with new ipads i could see a benefit. I am trying to figure out what traktor controller to get, I had the numark 4trak, and the traktor s2 mk1. I want it to be somewhat portable, but also good quality. I am actually leaning towards the s4 mk1 maybe I just dont know.
