Seeking Japanese Millet seeds

I'm seeking seeds for Japanese millet (Echinochloa frumentacea), or perhaps Japanese Barnyard Millet (Echinochloa esculenta), or any domestic cosun of Echinochloa crus-galli . I'm absolutely dippi over the wild Crus Galli grass, and would like to domesticate it. It grows so well here with zero human assistance. Since we have domestic cousins, I thought maybe they would grow well here too... or failing that, I could use them to domesticate the wild grass with a bit of breeding.

I'll be hunting the health food stores for the next week or so and picking up anything that resembles millet in the bulk bin, in hopes of getting something useful. The problem is, there are so many different plants harvested as 'millet' that it's not certain what I'm getting. But at least it's an affordable source of seed and I should be able to pick up enough to try cooking some too.

Does anyone know of a source for Japanese millet seed? Preferably an affordable source?
