Sandy -- As Gerald mentioned, TEA itself would work just fine. (In practice, that's what I use.) Barring that, of the options you listed, metaborate on its own is closest. A mixture of metaborate and borax could probably be used to bring the pH of the working solution even closer to the PC-TEA working pH but I don't know the exact amounts that would be required.
