I've had my own starter for... hmmm.... now that I'm thinking about it, it must be 10 or 15 years now. I've almost killed it several times, but it's hung on - lol. If I recall correctly, I used the very basic version found in the Tightwad Gazette to create mine. And the general recipe I used is also from there.
Good luck! But be aware that it's like having a "pet"... needs to be fed, used and cared for.
