Ok, so I want to be a DJ, have been for a while. I know the main concept, and I know about remixing and such. But I'm curious as to what the best equipment for price would be. I have a Macbook, and want to put a gig of ram into it, and I want to find a USB Turntable for MP3 mixing, to use with probably Traktor DJ Studio (I have used this before and love it) But, what else would I need, for now I'm just playing for school, and they have speakers I can use, but a good set of my own speakers for a good price is a good idea for the future. But I heard about an add on thing so you can actually preview your mixes and such, and you cannot do that with the built in sound card, I just need the basic stuff to get started.
