You're right about bang for the buck - that nothing comes close, seahps. With the CGP-700, Casio really did their homework on what was important to home users of a digital ensemble. All you have to do is look at the color screen navigation systems of the Casio CGP-700 versus the Korg Havian. The Casio has big, colorful, metro-style icons that invite you to jump in and start making music - while the Havian has a blocky text button interface that reminds me of the home-grown Windows programs of the 90's. But it just isn't Casio's great looks and ease of use. Important features like dual headphone jacks for lessons, an audio input with volume control, a dedicated tap tempo button, having the stand included in the price ($150 extra for the Havian), and an optional integrated 3-pedal board (Damper, Soft and Sostenuto). All in, the CGP-700 with stand and optional SP33 3-pedal board is literally half the price of the Korg Havian. To be fair, the Havian has many outstanding features the CGP-700 does not, such as a tone editor, about double the number of tones and styles, and song lyrics, a score generator with chords (Wow!) and jukebox, just to name a few. The Havian should be a good fit for a more technical user or performer with a bigger budget. However, for a total $875 for the CGP-700 and SP33, I do not feel that we made any important compromises for our grandsons - on the contrary, they now have a high quality digital piano ensemble that will be much used because it is a joy to play, sounds wonderful and will spark their musical imaginations.
