I'm building CNC Mill now and I know nothing about Good cheap Spindle for cutting metal.
I'm planning getting from ebay but I saw way too expensive and cheap.

Does anyone can recommend me what brand and any other accessories require to make the spindle run ? like controller ? etc ? can I use other brand controller ?

How about Kavo brand ?

My budget is less than US$ 1000, possible ?

Where can I learn the basic Spindle for this, the electronics, the mechanics, the theory of cutting metal, RPM, etc.. ?? any website about this ?

regards
