Hey,
Yeah, it's one hell of a keyboard, a friend of mine has one and he won't shut up about how good it is! What's nice about it is that it already comes with a ROM card with a lot of good sounds, so you can start making tunes as soon as you turn it on.
The sampler in it is amazing and the filters sound great, I have an Emu e6400 ultra which has the same architechture as the e-synth. If you're planning to do MPC style sampling, you're wasting your time with this guy, this is the kind of sampler that sound design guys use because it is so powerful.
The keyboard is really nice, it's a semi-weighted one identical to the one in my Kawai K-5000s, which is amazing. They feel solid, have a nice curve to them, and they transmit aftertouch. Awesome.
How much are they asking for it?
Take care,
Nick
