Greg - I'm not sure it's worth $80 - but then again I am a cheapass when it comes to golf books so insert that bias. I will say this: I refer to it A LOT for discussions in here and other things - I find it to be a very valuable reference tool. It lists the types of template golf holes and real-world examples of them better than any book I've ever heard of. if that's important or interesting to you, then by all means get the book. If it is pretty pictures or words of wisdom from modern-day architects you desire, then this book won't be for you.
I also own Paul Daley's series, and those are fantastic - they are just a totally different animal - far more fun, but far less of a reference tool.
