I'm a complete newbie to the CNC community. I've seen a mill in action but haven't had a go yet. Anyway, I'm going to get a mill to machine various shapes (2.5D) into acetate and later (when I feel more confident) marble. I've got the geometric side worked out in Solidworks.

What off-the-shelf CNC mill would be a good bet for pieces no larger than 1' x 1'. It will be for prototyping only. I was thinking Sieg kx3. Any comments or suggestions?
