HP 15c Collector's Edition US$145

This is the latest 2023 re-release of the HP-15C. Similar to the HP 15c LE, but with known bugs fixed, more memory, and slightly better performance.

Note: The 15c CE has a hidden HP-16C mode in it, with some bugs with its decimal mode. If you would like, I am willing to open the calculator packaging (which just requires slitting a small sticker) and install a corrected (but unofficial) firmware that fixes the most critical bugs before shipping it to you. Please request this at the time of purchase if you would like this service (at no additional cost). This fix is not supported by HP but seems to work, according to the community.
