The only commercially produced BSF unit available in the US now is the BioPod Plus. I stopped selling the original BioPod last year and I haven't gotten back into it since the new unit came out. I haven't tested the BioPod Plus so I can't recommend it at this time. I hope to test one soon and if the results are positive I'll begin promoting them.
You can buy the BioPod Plus from several dealers including the manufacturer ProtaCulture. Simply do a search for "biopod plus" and you should see the dealers in the results.
