MAD eBay prices

While searching for information on South American uniforms I came across this old eBay listing.
Even if the price [$425.00] is a misprint, paying that amount of postage [$35.00] for a CD! I’d want it delivered in person.
Also, better hope that the CD is of a higher standard than some of the Google and Kindle scans on offer.

I find e-pub great for text but very poor for images, yet there seems to be more and more image reference books appearing in e-pub.  
I must be using the wrong reader, I can manage to enlarge the text within a book but not the thumb nail size images that’s in them.

Question, has anyone found an e-pub book on Military History, uniforms and insignia that’s better than pdf ?
