Reply to Kontrol X1 or Xone 2d

It is time for me to get a new controller. Right now I use a Launchpad and mix 2 decks externally (umix44). I occasionally mix internally with a nanokontrol (prefer external) and use the loop recorder or an extra deck.

My question is, should I go with the x1 and upgrade my sound card later, with the 2d ad be able to mix 3 decks externally right away (3 chan mixer).

I am pretty on the fence right now, so any help would be great.

Also, I mainly mix 4/4 stuff (house tech house and minimal) and I am just as happy seeking with an encoder as I am a jog.both have to be better than buttons.

Cost isn't too much of an issue as I have found a used 2d for the same price as a used x1+ case.
