Elwood, I suggest you go look up the Casio MZ-2000. Casio can and HAS put out a semi-pro arranger in the $1,000 and up price range.

This new WK/CTK series (when looking at the WK-7500 and CTK-7000) would appear to be closer to what the MZ-2000 used to be. The current WK-3k series doesn't even come close.

These newer models (the upper units) have 16 track sequencers with event editing, ect. They have full style recorders for creating ORIGINAL styles and NOT the mix and match feature you find on the other Casio models. Casio has also brought back the 9 sliders! I would be very surprised if the Drawbar Organ feature on the WK/CTK was any less than the MZ-2000 (which had an amazing organ section by the way).

These new units have been COMPLETELY redesigned too. Don't forget that even though they may have dropped the TONE WITH WAV feature.., casio has added AUDIO recording to the two upper end units.

I'd be VERY surprised to see the 7500 hit the $500-$600 range. With the spec list (IMO) I see it getting closer to the $1,000 mark. Remember now.., the MZ-2000 was selling upwards of $1,300 as well.
