I'm fascinated too, but by all reports, this one is not for home cooks. Keller himself says he wrote this book for professionals only, and if you saw his book The French Laundry, you'd see that his idea of what home cooks can do is very expensive, idealistic, and time-consuming (like 18 hours per meal). In that book he says he adapted his recipes for home cooks. There was a website called French Laundry at Home -- she spent her entire weekend, every weekend cooking a couple recipes out of that book.

Sous vide equipment costs many thousands of dollars.
