I sold my CDjs to go down the traktor route... i have actually gone back to using Technics Turntables with time coded vinyl and Traktor Pro. Also using the X1 controller, AMAZING kit works fantastic, problem is, its not a case of IF, but a case of WHEN the laptop crashes. Even with a MAC you can still crash. I am going back to using CDjs and saving for 900s at the moment. I will still use traktor mainly for the FX units, but ultimately i have done both and you cant beat that hands on reliability of CDjs. You can still use Time coded CDs as well dont forget....
