Nice mixer for the price - Retailed for over $2000 at release.  

This is Josh Wink's mixer that he used along side Meat Beat Manifesto a few years back. It's in excellent shape. The crossfader isn't great for scratching, but otherwise it's a great dj mixer.

I like the filter efx and midi that works well with roland/boss drum machines....
