I used to collect guides too but stopped 4-5 years and now only buy 1 or 2 a year... but again, never spent $70 on a guide. I know the collectability of this guide is probably high but I'm buying this as a Zelda fan and it just doesn't sound like it's worth it. But, on the otherhand, I think Piggyback has a really good reputation for quality guides.
