Better idea save your money and put it towards the machine getting done quicker because although like John says it's a good read and very informative it does relate more to industry standards and Mach doesn't exactly follow them to the letter(At the moment.!). . . . Can't beat hands on experience IMO so get bloody cutting ASAP and learn along the way.
