$95 from Amazon or MIT Press, or $94.99 for the digital copy (you can save a penny!) though that's dated. Clicking through, it's $59.99 for the ebook from various sources. The ebooks are not PDFs, though, and so the formatting leaves something to be desired (based on samples). More complex math renderings are images that look ok. IIRC, there are some large code blocks in the book at some points but not in the samples so I can't evaluate them for clarity.
