Sima SFX-9/ -10/-11: Differences?

Good Morning!

Does any of you have experiences with the Sima SFX-Mixers?
(What do they have in common / what are the differences)?

It’s really hard, to find something on the internet (I found manuals of the SFX-10), but not of the 11.
In a short abstract NTSC / PAL inputs are mentioned (so I REALLY hope that PAL will work):



I’m a big fan of the SFX-M for its simplicity and ruggedness. I tried the 9, but preferred the M in the end.
