Native Instruments Traktor Kontrol Z1 - the little mixer that could. This one has seen a little light use in my Austin studio, so I will not call it perfect - but it is still minty fresh, works flawlessly, and comes in its original box. Compact 2-channel DJ mixer and audio interface for Traktor: hands-on levels, 3-band EQ, filters and cueing in a footprint smaller than your laptop. Perfect portable rig, or the heart of a modular Traktor setup with an X1 or F1. Its faders deserve better than sitting in a box - come and take it.
