Behringers BCD2000 was their first forray into the DJ interface/controller world and they say was very successful for them. So much so, that they brought out the BCD3000, presumably with features and tweaks that made it even more useful to the mobile DJ.
Designed to work with the laptop based DJ, the system integrates with NI's Traktor software - heck it ships with Traktion 3 LE so it should do.
Equipped with a USB 4-channel audio interface with mic/phono inputs, it should integrate into a standard setup with ease, or just plug it in to the house system to get grooving from your laptop. It also features a boatload of hands-on MIDI control and EQ/kill plus effects control.
Should be in the stores second quarter - so around april/may time and the price? Well it wouldnt be Behringer if the price was high..
