I can get all that stuff right by my house so I have never tried them, but they do sell good brands.
RU sure you can't buy fish sauce where you live? It is sold in lots of supermarkets.
But if you are going to buy it from this site, I suggest you get the "3 Crabs" or "Golden Boy" brands as they are higher quality. Those are a bit milder than "Squid" brand, another good brand. I use 3 Crabs, myself.
