hey guys. Here's my modest but practical setup
http://sphotos.ak.fbcdn.net/hphotos-..._3265472_n.jpg
Gateway NV53 laptop (2.1 ghz, 4gb ram)
1TB external hard drive
Traktor Scratch Pro
Behringer Xenyx mixer with USB interface
Stanton SCS.3 system
I love the xenyx mixer because it lets me have additionnal inputs and has its own effects board some of which are pretty cool. The SCS.3 is great because it lets me control the 4 decks in traktor.
In the near future i'll be getting a Midi fighter the make my setup slightly more versatile (ill use it mostly for effects and cue points). i also need a laptop stand badly! Last couple gigs killed my back from leaning over the stare at the laptop
eventually maybe a couple turntables...
