Routers

How many of you are using routers for cutting metal? Can you get enough
accuracy from a router? I've been using a Rotozip in my mill to test
the mill, but definitely need something better for making the parts I
want to make. Right now most of my parts will be wood, so the router
will be more than enough. Eventually I plan to cut some aluminum parts.
I'm wondering if a router can hold a decent tolerance.

I did cut some aluminum with the Rotozip and a 1/4" endmill. I was
making 1mm deep passes. The part did not need any accuracy to speak of.
The biggest problem with the Rotozip is that the collets are not
straight. A router would give much more power, but how are the spindles?
And can 1/8" collets be had?

Another note. I have been using a Minarik DC motor control to adjust
the speed of the Rotozip when cutting stuff like foam. All of these
types of power tools use universal motors which operate on AC or DC.
They can be had on Ebay for 20-40USD.
