Unfortunately this one has a crack by the headphone jack. Make sure to check out the links below, particularly the "Apocalypse Cow" video.
Some details:
"The Kawai K5000S is a turbo charged synthesizer with both samples and additive waveforms! The inclusion of an advanced arpeggiator, 20 realtime knobs (transmits CCs for control of other synths), 50 buttons, a nifty data wheel as well as a keyboard action that is to die for make this a very expressive instrument! The keyboard in itself is one of the best keyboard actions available in a synth today! What about the sound? The K5000s sounds uniquely rich and complex and cuts through the mix in any recorded track. It can sound like a Yamaha DX-7 but has a rounder edge to it's tone...if a digital synthesizer can sound warm and organic, this synth would be the answer. In a world of copycat technology and design, the K5000S is probably the most esoteric synth to have ever been produced, crossing the line between evolving digital and analog timbres with full control over it's parameters...and there are a lot of parameters!!! This synth is very very spacey!!!!"
