Jan I did the same thing. The Kn7000 was a bit heavy so I purchased a Kn2600. After the second job I never used it again. Many of the features that made the Kn7000 such a special instrument were not in the Kn2600.They left too many things out making it a disappointment.
If I never had a Kn7000 maybe I might have thought differently; but it was lie going backwards. I bought a used Yamaha Psr900 instead. It was a good keyboard but I went back to the kn7000 for another 12 years.
Only my opinion, JohnC.
