Reply to Sound Cards

Hey DJ tech tools..

I Am currently in need of a usb external Sound card, but I don't know which is the best to get.

I am running Traktor Pro and using a VCI-100 XD..

I am after a sound card that I will be able to plug speakers into and headphones.

(I live in Australia so the prices on the sound cards are more expensive....Does anyone know where i can buy them in america for cheap?)

If you can help me ASAP that would be saweeett XD thanks guys
