Probably the wrong thread for this, but I have a couple thoughts about Kurzweil (whining - ha ha).
For my own preferences, Kurzweil seems to be going in the wrong direction.
I had a K2600, and I consider that their pinnacle.
By this, I mean they are adding things like streaming, and following the trend of more sound/patch material, and taking away the things that I consider are more important.
The new keyboards no longer have a ribbon or breath control input, they have less audio outputs, and control pedal inputs.
Some don't have aftertouch or a sequencer either.
My ideal keyboard would have the dual ribbons and breath control input, the nine sliders accompanied by nine knobs, and the setup controller capabilities of the the K series.
Yes - I know - maybe I should have kept the 2600.
If it were about 1/3 the weight, I probably would have.
As a non-gigging home hobbyist, I use a computer for most of my sounds, and a keyboard as my main controller.
A gutted 2600, even without any sound producing capability, but with all the controller capability intact, along with a massive weight reduction program would find me in a buying position again.

sorry for the thread derail, but it feels good to get that off my chest.
