I would like to debunk the CNC should make it cheaper mentality. Using a CNC is about consistency, not labor savings. Yes, when making nuts, bolts screws that make thousands of items a day you can save labor in that you only need one guy three shifts. however it is only optimum for non-batch processes. And it still requires set up time.
As far as the CNC and luthier grade custom guitars, while they are amazing machines they still can only do what is called "near net shape". And it is a batch process. You are making at best very short runs (1-3 pieces) because no two are exactly alike. So you spend time setting up the CNC for at best say up to 10 pieces. takes time.
Then you let the machine do its magic. then you take the pieces out and the rest goes by hand.
After the router and drilling ops are done you still have sanding to do. A CNC only does the normally repetitive stuff that you can pay any guy off the street to do. So while there is a savings in labor it is not what you would think.
Spector, Tobias (MTD), dingwall and many others use CNC for shaping bodies and doing early neck work. But with any instrument most of the labor is in the sanding, shaving and detail work. That is not to say you can't do it all with machines, but luthier grade instruments are not. Hell, Phil Kubicki is legendary for the necks he made and he used a series of milling machines that would be the equivalent of today's CNC. He still did an enormous amount of fine shaping and tuning. And his necks weren't cheap.
So while there is some efficiency in using a CNC, in small batches it isn't the savings you think and it really is more about consistency in near net shaping over the same manual hand processes.
While I never agreed with Ed Roman on a lot of things his discussion of them here is interesting: http://www.edroman.com/rants/cncmachines.htm
Note what he says, a CNC can't do the matching, the material selection, the wood acoustic choice, it can only cut consistently. Which is not where most of the cost of a custom instrument is. It is in the detail work and human touch.
Having worked with and known some of the legendary custom builders the point made a few posts ago is actually more true then you think. Many luthiers have more creative talent then business sense and do underpay themselves. Note that the Rick Turner's of the world are not millionaires, and that most luthiers don't get real money until they sell their companies.
