Hewlett Packard HP 17bII+ Scientific Calculator

The HP-17BII+ calculator works well as a financial or scientific calculator. Nevertheless, the original HP-17BII (not the + model) is much desirable. Although the BII+ shows some new capabilities, the keystrokes are very similar and the 17BII+ has a cheap feel to the buttons when pressed and sometimes the number or function doesn't register when the button is pressed (welcome to cost cutting!).

You will not have any problem to find a HP-17BII on eBay today and I think it is a better investment than the BII+. The 17BII has been produced first in Singapor (we can identify it because it shows 5 rubber feet on the back) and secondly in Indonesia (this one shows 3 rubber feet only on the back). The singaporian model is the one to look for, particularly if you are a collector. Keep an Indonesian model if you like variations and because it is a better model than the 17BII+. The nostalgic users will seek for a 17B which is the less powerfull but the oldest model. The collector will seek also for the black variation of the Indonesian model.
