i also agree with esmee but if you goiing to ad a third cdj or a turntable i would go with a ddm4000. the ddm4000 is not as bad like most people here think. its a very good player and i used it once and liked it very mutch.
but if you not goiing to ad something i would go for the djm 400
i used it once too, and i suprised...
that good mixer from, behringer....
i decide that i'm gonna buy cdjs with behringer mixer..
