The original two Guides have now been replaced with a book,
Enduring Design: The Romance of the Atomic Coffee Maker, also available as an eBook. Chapters on the history (and legends), the evolution of the design, care and maintenance, valuation and even making coffee. The book is at
Blurb.com and the eBook is on eBay, well sometimes anyway.
Initial reaction has been excellent, but this is no doubt because there is so little previously published. Keep an eye out here for corrections and revisions, because this is where you will see them first.
