Reply to Best Traktor controller to suit...

Ok so I want to change my approach and needs for Traktor...

Im after recommendations for a single or 2 controller(s) for 4 decks to use with Traktor:

Adjust & bend pitch (Ideally jogs & pitch fader)
Control - loops / cue points
scroll & load tracks
control efects

I will then be using a external mixer to mix on.

Any advice would be great
