Vestax PMC-05ProIV

This unit mixes computer, CDs, and phonographs. Some of its controls are MIDI-assignable. It has 2 channels. Comes in red or black. Since it is not a sound card, just a MIDI controller, to get two channels of stereo from computer to this mixer, one also needs a multi-channel audio box compatible with the computer.

KORG Zero4

MIDI, Firewire audio, 4 channels, BPM-based sampling, effects, phono/line/midi/audio control, i.e. almost everything in one place (except deck control). Unfortunately, KORG discontinued the Zero4 (and Zero8) not long after they were introduced in 2007. The retail price was $1299. Glowing review: http://www.skratchworx.com/reviews/zero4.php This item is rare even on eBay. As of 2010-11-15, there are four for sale there, two from Japan and two from UK, all new in box.
