Siemens used to be quite expensive, but they have really driven down their prices.
I just saw this: https://support.industry.siemens.com/forum/WW/en/posts/g120c-for-high-frequency-spindle/212907 So the S120 is the drive to use for high freqs. I've worked with Yaskawa drives in the past and the Siemens drives are easier to use. Plus Siemens phone and website support is really good and free.
