Reply to HELP Choosing soundcard for Live

Alright so I am trying to get everything I need for my ableton live setup. In mind I have the VCM 600, Launchpad and a soundcard. idk which soundcard to get either the Audio 2 or Audio 6. Which one is sufficient enough for ableton? and since I am really new to Dj-ing, can I cue with the Audio 2 or no? If i use 4 channels to DJ in ableton, can I use the Audio 2? Im just trying to find the most cheap soundcard for the setup
