Unless you want something paper in front of you, don't bother with this book. It is very short and 80% of the content is covered in the Getting Started manual. If you really just want to learn the basics of Jmeter I guess it would be a good book, but other than that it is not worth the crazy price of admission. The illustrations would done well and the font was nice and large - but that somewhat irritated me also, given how small the book was, so I felt I got more ripped off.
