Trading in EOTN

Where's the best place to buy and sell in EOTN?

I don't think any place has been established as the trade center, as many people go back to LA, Kamadan, or kaineng. But I'd guess the EotN would be the best place in GW:EN.

I see a lot of commerce in Sifhalla and Eye of the North. The Eye seems to be the ideal spot. It's centrally located. It's always crowded and it's design makes it easy to find people. Nice open round chamber unlike LA or Kaineng which have you running all over the place looking for storage and the merchant and the rare material guy and then the armor guy and then.....
