What's the best equipment to mix music/DJ on? List everything needed please.
You could use Native-Instruments Traktor S4 - http://www.native-instruments.com/en/products/traktor/dj-controller/traktor-kontrol-s4/ and some basic power computer speakers like the Creative GigaWorks T40 II - http://www.amazon.com/gp/product/B001S14DYO?ie=UTF8&tag=pbmo-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B001S14DYO. And then upgrade to the much louder Pioneer S-DJ08. If you want to save a bit of money up-front to learn then use the speaker setup you already have and just use Virtual DJ Home (free) - http://www.virtualdj.com/products/homefree.html
