Zen Goban
Zen Goban is a direct importer of Go Boards, Go Stones, and Go Bowls. It is based in Winter Garden, Florida (USA).
From their website: "Zen Goban , Simply perfect Go supplies" and "The main focus of our business is to bring a quality product, at competitive prices, to our customers."
At the moment (July 2010) they only have a small assortment of (what looks) quality boards, stones and bowls all imported from China,
Their main market is North America but they are willing to export to the rest of the world.
