I take note of this hudendai auction.
I give the seller credit for close up photography, since it makes it clear that his asking price and the condition of bezel and faceplate are quite mismatched, even if the thing comes with a manual. This calculator is not nearly in as good shape as the asking price would suggest.
In July, I paid $282US for my 15C. No manual. I thought at the time I was soaked. But the thing is perfect, apart from evidence of slight peeling of the protective coating over the display, and I probably did that myself. No scratches on bezel or faceplate. No nicks in the plastic. No dust in display. Info plate perfect. Feet near new. The seller said the thing was like new and he wasn't lying. It is the only HP calculator I own that I keep in the case all the time and rarely use, preferring my cheaper and more beaten up 11C for routine Voyageur calculation.
I did not have a year full of cheap estate sale finds and big bargains, but when I see stuff like this, I feel pretty lucky. Considering how some guys spend thousands a year on golf memberships and other big budget hobbies, calculator collecting is still a pretty cheap vice, even if I am not a great bargain hunter.
Happy NY again to all!
