HP 20b Financial Calculator

Back ordered until Dec 22.

The HP 20b is their entry-level RPN financial calculator. It is aimed primarily at students in real estate, finance, accounting, and business.

It is the best bargain in the financial calculator market, with some advanced features found on no other financial calculators, while being sold at a low price -- the cheapest RPN calculator available.

Note: For international deliveries, I can ship it in an envelope instead of a box, reducing the shipping fee to US$15 (instead of $27+). However, the calculator is not quite as well protected in an envelope. Please email me for details.
