First time poster so please be gentle!
I'm currently looking to reinvest in some decks. I've heard on the street that the S4 is a pretty cool little device that can do most things I need it to.. however from reviewing most of the posts is this worth the buy as there seems to be lots of complaints and such.
My other option is either a Xone 4d (Ideally steering towards) or 2x CDJ850k's and a DJM700 mixer.
Any help is appreiciated.
