That Korg thing is pap...dont bother. Kaos pad is gimicy, eqs are horrible and flimsy. Faders are to my taste but definatly not everyones. Trying this one before you buy could sway you massively (but dont concentrate on the pad as otherwise you forget how shit the whole package is)
Personally a mixer is the only thing I wouldnt buy 2nd hand, just me tho propbably.
