Hi RC
I have made enquries locally i=n SA, and the book is available. I should be able to get one during the week, since we are about 2 hours from a major centre.
I have also been the website you mentioned, and I was impressed. My mom has always suffered from sciatica and dad has had 2 fusions. I will also certainly get them a copy of the book to help them too.
I will let you know how it goes once I have my hands on the book and I have photoread and started to use it.
Regards Colin
