Don't forget to include the carriages in the cost estimate.

You'd be just about okay with a 1200mm 2010 screw @ 1500rpm.

Those of us using steppers rather than servos don't tend to go above 10m/min because the steppers will really lose torque above 1k rpm. My machine can just about handle 15m/min, but I'm leaving it at 10.

You'll have to find build logs for comparable routers using servos - I don't have any experience with them so won't advise.
