Amazing keyboard! Sample quality is excellent with a full set of GM sounds and over 200 additional sounds. The piano action keyboard is great and although it's not weighted it feels substantial. Interfaces are superb - I run it through the studio speakers, it talks to our PC via USB and I've attached a standard Casio foot pedal to the pedal input jack. By the way, the "Click Organ" sample is worth the money on its own - add a little overdrive and you have a classic rock Hammond sound!
