What mainstream brands (besides Rummo, which is good and thankfully widely available in Switzerland) would you recommend?
La Molisana is also OK among the commercial ones.
But if you have the chance to find it, you should try some pasta from Gragnano, they normally have pretty small businesses, so it is not so easy to find abroad.
If so, I'm in luck. It can be absolutely mail ordered and I'll definitely give it a shot.
Thanks a lot. Your tips are much appreciated and will probably lead me to eating better pasta. :)
