Just trundled over to Amazon to poke forlornly at the The Unorthodox Engineers listing to see if there's an affordable copy -- and found that it was released in ebook format by Gateway back in September. I think DRMed, alas, but at least it's available. 30 seconds later I was logged into my Kobo account and chucking a couple of quid at the Kobo server...
Gateway have several other books by Kapp in their ebook catalogue, so I may add to my collection.
