What I really loved about the talk is that you got a good insight into the actual complexities of manufacturing and drew all the right conclusions from it, rather than to throw your hands up and ordering stuff from China after all.
Friends of mine - with a bit more practical experience - are doing something similar, they realize that if there ever is a real demand for their product it might be at a time when the cheap alternatives simply are no longer available and have set up from day #1 to do everything in Europe. They are - like you - quite talented but the difference is that they have access to a lot more funding and if they need a particular machine they will simply go get it rather than to make their own.
You are resource constrained and that brings out a lot of creativity, which in the longer term will turn into a competitive advantage.
