Tonight at my Hackerspace, a local maker brought in his Kickstarter project. It is called "MezzoMill." It is CNC specific to small PCBs. The intent of the project is making it (nearly) as simple as printing from Eagle. There's no need to change bit sizes more than once and the entire process is automated.
I was really impressed with the ease of use and the results of the board. I thought others might be interested in seeing it as well. I'll probably back the project, just not sure what level yet.
Here's a web page on the CNC which links to the kickstarter project:http://mezzomill.com/MezzoMill/Home.html
