Regardless of whether you get a manual mill or CNC, buy an insert face mill along with the regular stuff.

Fly cutters will get you a better surface finish if you go quickly and have your head very square. See 4:25 in this video for a pretty cool demonstration of a good fly cutter:

I use face mills when using big rigid machines, but I've actually found that a sharp flycutter in aluminum can do a good job too.
