HP 17bII+ Financial Calculator, 22-Digit LCD

This is my second HP 17 B and my forth HP calculator over a period of about 28 years. Here is what makes the 17BII special: 1. Uncluttered keyboard - this is the result of the soft keys (across the top row) and menu options. This makes it much easier to see what is on the keys. 2. The vertical layout (as apposed to the horizontal layout of the 12 C). Vertical fits better into one's hand. 3. The screen is very clear - I think it is better than the 12 C. 4. RPN rocks ! (the cheaper HP financial calculator does not offer an RPN option). The ease of recalling recently keyed numbers and results, rolling down the stack and being able to store / recall numbers in the registers is soooooo nice. 5. The back-space key is terrific - I use it all the time. As with other HP calculators, the keys have a solid feel - considerably better than what one finds on cheap calculators. I use the calculator every day at work and generally get 6 - 8 years out of them. Other HP calculators I have used over the years are the 12 C and the 41 CV - the 17bII is my favorite, though the 41 CV was a really nice machine (a bit overkill for what I do on a calculator these days, and I don't think they make them any more).
