Thank you for the welcome and suggestions. Unfortunately I live in Italy (where customs are an hell lottery). I watched just yesterday the Topre and yes, probably, they are the best choice for my needs but, unfortunately, they are also very expensive (for me, in Italy).
I would like to try MX Red and MX Brown in the next days. Now I am using MX Black and MX Clear but I would like to try something with lower activation force.
Topre (and Filco) are on top of the list but, for try, I think I will buy some QPAD, less expensive in Europe, to try these MX switches.
I am also searching for something with IT layout for my girlfriend (she works 10 hours a day with the keyboard) but Topre is not available with European layouts and she needs it.
Thank you!
