Hi, if you run a search in the food forum (where food-related items are), you'll find some answers such as Yi-wei foods
(dried, in bags, not in oil), and if you run the search on just thread (topic) titles, returning results as threads, you'll see that there's an existing thread on this. I realize you may have found that but wanted fresher info; no worries, I'll merge this for you, as it's best to keep just one thread per item type, so future searchers don't have to open multiple threads looking for info.
BTW, Costco has been out of the oil-packed ones for a while. Damned shame, too, as they were reasonably priced, and good. I imagine Wellman's and Jason's (see my post from 5 years ago) and other import supers will have them, but at high prices.
