I played a long list of Technics stuff starting with organs about 35 years ago. I still have KN7000's but have gone back to organs with the Roland AT350C as my primary keyboard at home. I use the AT350C for the most part as an arranger.
I tried a Korg PA3X for about 6 months then sold it. Tried a Roland BK-5 and although I still have it I don't use it at all except for occasional style editing. I don't like it at all for live playing. I still depend on the KN7000's for stuff outside the house. If I lost access to a KN7000 I would probably opt for the Korg PA3X or PA900.
