I'd say for keyboard, Axiom Pro 49 is awesome all rounder.
For MPC pads, the KORG padKontrol is awesome with its X/Y control pad.
For mixer hands on control, the Behringer BCF2000 with a few knobs and 8 motorized faders for a very ,very cheap price and if you want more knob control, try the BCR2000
Those 3 cover the basics you'll need to begin with and they are all solid and quite cheap.
You're Welcome ^_^
