Dan:
As to milling machine:   Milling cutters are expensive and don't stay  
sharp for ever.  I don't know any one who can sharpen them  well on a
bench grinder.  A good tool and cutter grinder will pay for itself when
compared to buying new cutters every time one gets dull.  You can save
on cutter sharpening if you use a saw to remove as much stock as
possible before you mill the part to dimension.

I notice several on the list like  the  metal cutting band saw. I make
the same suggestion.  Grizzly, Tool Town, and Harbor Freight have
serviceable ones built like the Do All which can be used to cut off
stock up to 4 inches in thickness, or with the accessory table, used
like a " jig saw" for cutting large radius curves.

Cutting tools such as milling cutters as well as saw blades are  
designed specifically for the material you are going to try and cut.   
Brass isn't as gummy as aluminum and plastic is worse still.  Some
things are very abrasive.  Plastics containing glass and believe it or
not, teak lumber will take the edge off any tool in short order.  Teak
has a lot of silica in it.  I think you will find that though brass and
aluminum have their uses, they are harder to work with than steel.
