However, I don't agree with what you're saying about manual mills only being used in profit-losing situations. There are still plenty of machine shops effectively using manual mills to make parts.

If you don't already, I would highly recommend switching to insert face mills over end mills and flycutters when you can. You get absolutely stunning finishes while running the things at 2000 or 3000rpm. I run a 2" face mill at 2000rpm on a manual mill and it has greatly sped up how fast I do my work, because I don't have to take a finishing cut and I can chug through metal really fast.
Regardless of whether you get a manual mill or CNC, buy an insert face mill along with the regular stuff.
