I just did my 4th edit, and am now offering a really cool, low-cost version (b&w inside) via Lulu and Amazon. The PDF download is priced at $3.99 for a limited time. Take a look – nothing that keeps you from buying multiple copies btw;). If you want the dead-tree version Amazon.com sells it, as well (but I prefer if you bought from Lulu.com). My other Lulu books are here btw (Music 2.0 etc).
