They’re resellers, with apparently ridiculously high prices.
Mazzer direct is the place:

Mine was about £900 landed.
Versus the Duo- for me I was never a huge fan of how the Niche looks but gave it a try for switching between filter/espresso. Ultimately although it’s a brilliant grinder, I wasn’t hugely impressed with the filter from it and struggled with espresso shots immediately after filter ones.
I also prefer the balance of body/clarity from 64mm burrs.
If you’re only using it for espresso, I don’t know if you’d see huge improvements in the cup on your SSP based grinder. I can’t say for sure as I’ve never tried the SSP burrs.
Edit: I noticed the Mazzer page is down. They might’ve sold out.
