I run VDJ 5 with the Native Instruments Audio 4 DJ Sound Card, and 1 Stanton C.304 CD deck. I love it. I started on a cracked version, and liked it, but was hesitant because I ran across lots of bugs. But since I had bought the Numark Total Control earlier, I was able to get VDJ Pro at a HUGE discount. Since I bought the legit version of the program, I have been happier than a punk in a prison.
Spun an event live side by side with a friend who runs Serato, and had him over at my rig asking me questions about why my mix sounded so good while I made it look so effortless. No I don't use automix or any of that "cheating" stuff.
