I have a Mini rather than Micra but can echo the above comments. I had a manual profiling machine before and didn’t really use it.
Incredibly consistent, reliable and if access to the global parts/service network is important as in your post, there’s arguably not a better choice of manufacturer.
Having said that, it’s also a very easy machine to service yourself with low-cost parts. I just did the annual service on mine and I think parts (gasket, screen and dispersion screw) were less than $20 total.
