as I said in the thread about the DVS's, I'm looking to buy a DVS. the main reason I want it is simply to have access to all of my tracks and have them better organized.

I was looking into traktor scratch duo and it looks pretty good to me (as well as the price). can anyone care to give feedback on it?

I'm going to mainly be using it on my desktop, and also plan on using it with my laptop whenever I do play out (which is pretty rare). is there any issues with installing the software on both laptop and desktop? or is there a unique key that allows me to only install it to one computer?

also, currently I have 2 CDJ 200s and a DJM 400. are there any issues with hooking it up to that?
