Free Update: v1.2.1 of "The Big Book of Helix Tips& Tricks" Now Available in Helix Posted Saturday at 07:44 AM If it means that much to you - Inkjet printer, ream of A4, several spare cartridges... My Grandfather used to own a printing business... I'd be willing to bet that it'd be cheaper to 'do it yourself' than what would be a reasonable retail price for a professionally produced book - even if you don't own an inkjet printer to begin with. Last time I had some pdfs printed out at a local print service, it was something like 12p per page. That'd be about £55 ($67 US) for just an A4 paper print. If you want an idea of how much you'd have to pay for it in a book format, get on Amazon and look up Burst Believers or the PAF Myths & Reality books, and bare in mind they don't have 450+ pages.
