For anyone who has been holding out on buying the Billie Hougart text, there are a few of the latest editions available for $70 OBO currently on eBay. I offered $50, and the seller counter-offered at $60 (which was what I wanted to pay in the first place!) You can also purchase the text directly from Mr. Hougart’s website for $70 too.
