Converting Rhino Drawings to G-Code?

I'm pretty sure i'm decided to use Rhino as my CAD program. I've
started looking into what CAM software to use and now I'm just as
lost again. What do you people use?

Visual Mill 4.0 is available with Rhino as a package so I'm guessing
Visual mill 4 would work great with it. But theres no way I can
afford that right now. Has anybody tried to use the free version of
Visual mill (3.0) to convert Rhino drawings?

Are there any other programs that are fairly cheap (or free!) that I
could use? Thanks in advance.
