I've seen the Taig in action at an exhibition and it looks pretty capable.

I may be prejudiced but from your description of what you want to do I think a router-derived gantry machine is unlikely to be rigid and precise enough. I think I have seen a Nomad machine in a university student workshop and it seems quite restricted in trying to lock you into their software - also it is essentially a gantry router. It's when you want to start machining steel and small parts such as watch bridges that rigidity and precision start to matter, but also "engine turning" type work might look wrong if the machine isn't sufficiently precise.
