Well the cost is all in the bearings - if you put in ceramic P4 bearings then the cost of the bearings is as much as the spindle!
its all a bit of compromise I think.
I just ordered a 2.2KW 8 AMPs from HK - China - cost me around 300USD, I am assuming it has steel ball bearing - ones those give up I need to move em upto something better P4 graded.
after all routers screaming at 24K rpm dont have ceramic ball bearing.
so I am assuming its worth a try.
I have ordered a Delta VFD to run the spindle.
