Actually the kit I got comes from karma cultures, which has a store right here in Inglewood, though I've never been. I got the one gallon kit.. basically a glass jar, tea, sugar, and your first scoby. Strainers, ladles as well. The scoby will duplicate after every batch (about one week). Karma cultures sells them for $40 but as I go on with it, I may just start giving scobys away :-)

Decent intro on it. Oh and robotic my first batch tasted better than my fav store bought.. a little more tea flavour in it. The possibilities are endless making it at home
