I've heard that the best ones go to Japan where they get big money for them, but it sucks that you who live there can't get your hands on just a few. Go to the Amazon and try to find people who know their stuff that you like and like you back. Surely you will find someone who can help you.
See you after Covid (whenever that happens) and best of luck with the new job involving travel. Take your masks. Poor Brazil is in a mess as far as the virus goes.
