With four supported number bases, extremely long battery life, user-selectable word sizes, and variable register sizes, the HP-16c was in a class of its own that hasn't had a rival produced in the last 24 years. In fact HP has not made an RPN calculator dedicated to programmer's since the 16c

- An 16C in good condition, with the case and manual can go for over $300 on eBay.
- HP still produces the 12c and brought back a limited edition of the 15c. It's time for a 16c comeback!

A petition was able to bring back a 15c, let's give the HP-16c the same honour!
