+ rep I have an ns6 too and I can guaranteeing you it's solid as hell, feels more solid than cdj's to be honnest. Everything from the tightness of the platters to the resistance on the faders is top notch. as djim said, there are crap quality controllers just as there are crap quality cdj's, but if you look around you will be able to find those vastly superior units. The fact that people claim that cdj's are better than software is abit hypocritical, seeing as you have to have software in some way for a device to function, for example you can't run a computer without a bios or an OS.
