Do you have a copy of A Guide to HP Handheld Calculators and Computers? An excellent reference when building one's collection. There are so many detailed differences within a series or even a particular model that I find it useful to do some research first. Of course the forum member's recommendations/comments are useful and entertaining, too.

Thanks for the info, that book is a good recommendation for anyone in this hobby.
Probably it will be one of my next acquisitions too.

Clearly the 17BII can be found in quantities at a low prices in several sites besides the eBay, but the story with the 14B is different, so perhaps the latter is more valuable from a point of a collectors view.
