Hi, lots of recents posts on picking your new controller. I suggest reading some of them.
The MTP3 is on our shortlist of good starter controllers, together with Pioneer DDJ-SB2 (or DDJ-RB if you are sure about using RekordBox DJ software), Denon MC2000 (and a bit more money) the MC4000 and the Reloop BeatMix 2.
The decicion-making process starts with determining your (desired/intended) workflow, picking your software that most closely matches your workflow, setting a budget and then shortlisting 2-3 controllers that support your workflow, your software and your budget.
Hope that helps some.
