I am interested in ONE of the various new Casio models -- but I'm not sure about the keyboard quality differences between thesse models (which are more or less similar, save the sequencer and drawbar features):

WK-7500
CTK-7000 (key count only?)

WK-6500
CTK-6000(ditto above)

CTK-5000

I'm hoping George Kaye or some other dealer might be able to help. The Casio site info is quite good -- Whjat I really need are comparisons of the quality-feel of the keypad. I am not really in need of the organ functions or sequencer .... for example.

Thanks ahead for any help available.
