I got a few 50 gram packs from iBrew.com.au last year... enough to last for quite a while and with the exchange rate, the shipping from Australia wasn't prohibitive at all. Apparently, this will be available stateside sometime in the next month or two according to Denny and Drew on their Experimental Homebrewing podcast.
If you don't want to wait... I can spare one packet for $10 plus postage... probably a couple of bucks in a padded envelope. PM me if you're interested.
