I tried once to deal directly with the manufacturer. Very nice folks in Thailand. The pots were very affordable, the shipping wasn't! I would have had to buy a minimum of 4 cases and they would go air freight. I ended up buying from the Survival School in the UK. Johnny Crockett was very helpful and the shipping was fair. They were much less than RM, still way expensive.
One thing I don't like about them, they are built like a tank, very sturdy. If you are planning on packing these on your back, that means heavy!
