Numark N4 (Serato Intro, VDJ) or Kontrol S2 (Traktor Pro 2)

Well depends on what you do and how you do it.. for me the Numark N4 is the better option because of the four full channels (and I plan to buy it soon) and the Serato Intro feature, also you have the vDJ’s timecode option open if you want to go down that route.
