Reply to Mixtrack vs Mixtrack Pro

Hi there,

I'm looking to buy myself a new controller. I don't want anything too expensive, so I've set my budget at about $300-$400. I'm still a beginner and this is just a hobby for me, so nothing too fancy

I've looked around and I believe I'm down to either the Mixtrack or the Mixtrack Pro. Of course, if I get the Mixtrack I need a soundcard and I've seen the Audio 2 suggested a few times here.
So it's basically
1) Mixtrack + Audio 2 (or another soundcard)
2) Mixtrack Pro
3) A different controller

I'm hoping for some help in making my decision, so any input is greatly appreciated.

Thanks,
