I need to equip my R2E4 with an add-on high-speed spindle for drilling
and milling PCB prototypes.

The little 1.5KW water-cooled spindles from China look attractive. *With
one of those, a matching 400Hz inverter, and a little cobbling, it looks
like I can get into service for under $500.

Does anyone have any experience with those, any brand recommendations,
life-expectancy, etc??

Thanks,

G'luck with it.

Probably want to think about adding the cost of a small water chiller
unit also.
