Thanks @BradT and @AllenMassey for the answer 
i have to think what choose, first between the gShield and CNC Shield, i think i choose the CNC Shield, with the same drivers of @BradT, instead for the spindle or the router, I don’t know what choose. If I buy the quiet spindle (cheap 30$ dollar on China website, same model as here I think) I have to buy also the power supply, because I don’t think one power supply for controller motors and spindle is the right choice, what you think?
I have also found this topic:

And think that maybe I get the broken router, I spent more money for nothing…
Very hard choice 
Just to know, since I live in Italy, and we have the 220-240V, if I buy the dewalt from US,(my sister live in US) I can use it in Italy? Obviously with a plug adapter? Because I have see that on homedepot cost around 100$
