Looking for Controller replacement, a dilemma.

[theconsole]

Hi, I am currently mixing with a DJ Tech X10 and a Launchpad. The X10 has a pretty good sound card and usb ports are great.
The Launchpad mappiing gives my control over 4 decks of, hot cues, sync, all looping function,transport , and even track and folder navigation. However, it feels weird using a controller laid out for Ableton.
I did have a Mixtrack but I sold it because I felt it was too big for the amount of functionality you got.
I am currently looking for a Stanton Djc4 as replacement. It fits in my gear bag.
Soo, I got to thinking....


Should I get the djc4? Would it sound better? IF it did not, could i use 4 decks with my Audio 2?
I certainly would have a bit more functionality and I do miss pitch controls and jogwheels. Would this be an improvement?
: I am thinking it also would be more portable, less cables and all in one.
Or is it better to keep the Launchpad setup, the external mixer, and add an X1?

Decisions ,Decisions. Need help. Thanks guys.
