The Register reports about one Cisco CCNA Manual for free. I downloaded the copy and it looks extensive and the hard copy is sold at Lulu for $25. Upon preliminary examination the book looks OK, but than I would still spend $40 on Amazon for this book, as with the book I get exam questions along with simulations and other electronic material and allways use this as a reference material. But this is a good effort.
