Ketron SD9 reliability

Hi all, I'm currently thinking of replacing my SD1 with a SD9. Can anyone confirm that it is reliable to play live? Thanks a lot.

SD9 has been reliable for me live, I did use SD1, and later on Audya 5 as my main keyboard prior.

Good to hear then, I have no experience with this keyboard at all.

I was just puzzled since I tried quickly an SD7 recently and after 5-10 minutes of playing with it, nothing fancy, just trying around styles and sounds, it froze and I had to restart it.
