+1 for the “How to digital DJ fast”, this one is complete course that will teach you basics on controler setup, there is nothing similar on the internet
There is also a cheaper version of that one that will teach you how to do all that on Virtual DJ Home: http://www.digitaldjtips.com/learn-to-dj-with-virtual-dj-home-free/ for only 9$.
If you are really into a DJing then I would go on first option, but if you are exploring DJing atm and don’t know anything about technical side of it then save your money and try second course.
Hope this will help you on your decision, cheers!
