Reply to Midi Keyboard? Maschine or Maschine Mikro?

So I am getting into making this new music making obsession. I was just curious if anyone knew or could recommend a good buy relatively inexpensive midi keyboard. I am a college student on a bit of a tight budget... And also should I get Maschine or Maschine Mikro? I know they are both relatively the same but I'm not sure which one people were suggesting. All the help I can get would be awesome. www.soundcloud.com/gagnon23
