I bought this book before I even got my etx125 a few moths ago, having seen it featured on "weasners mighty etx" website and i've read it cover to cover three times.
Not only does it provide invaluable information on caring for and servicing your telescope, it gives you an impartial and realistic expectation of what can actually be seen with these little beauties.
As anyone who takes up astronomy as a hobby will know - telescope manufacturers often exaggerate the abilities of their product and infer that you are actually buying the Hubble space telescope by printing highly resolved images of nebulae and galaxies on the box and in the manual - this book will give you a good overview of objects to be seen and how you will see them.
The book also serves as a beginners guide to astronomy and, whilst it primarily covers the ETX90, is relevant not only to the other scopes in the ETX range but to small telescopes in general giving tips to novices and old hands alike. For complete beginners it explains, in laymans terms, astronomical jargon and sheds light on some crucial equations and factors that anyone into this thing needs to know, showing how to calculate magnification and which eyepiece is best for any given application etc.
In short, I would recommend this book to anyone interested in astronomy and would go as far as to say that it is a crucial purchase for anyone who owns, or is considering investing in a Meade etx telescope - and, believe me, they are an investment!
