Pad Plus- How much value should I put in it?

Pad Plus- How much value should I put in it?

I am trying to settle in on a controller. I mix mostly trance/deep house type stuff and enjoy running the same track parallel and layering effects. Having 4 faders is nice for this, however the Pad Plus on the DDJ-SR looks really interesting.

Is it really enough of a cool feature to focus on the SR over a used or Refurb SX? The SR still has 4 deck control, just with soft takeovers.

The Terminal Mix 8 is also on the radar if any of you have played with one.
