Default using linear motors to build a small cnc

Has anybody built a small cnc using linear motors?
I am toying with the idea of building a small high speed mill/router and am
wondering if using linear motors is a good idea and where to find some.
Brand names seem pretty expensive.
I would like to have feedrates of at least 1000 ipm so that eliminates
stepper motors.
Travels would be at least 12" if not 24" on all 3 axes.

Also, what could be used for spindle? Ideally 10,000 rpm
