Yes, I agee on the costs.
Many of my choices would be different if I did not do things for commercial uses.
Haas has the lowest costs in the industry.

A servo amplifier (ie driver) (just electronics) costs 500€.
The same from yakawa or siemens costs 2500€.
The ones I use cost about 350 for the same size, circa 1kW.

Like I said, the MPG wheel is only 30 or 40.
