To me,
it's odd that hp still makes financial rpn calculators but not scientific ones.
The scientific RPN models are the 35s and the (possibly discontinued)
15C Limited Edition. The 20b and 30b financials include scientific
functions.

Steve,
You are correct. Unfortunately the quality and key response is poor. Only a finite number
of the 15c limited edition were made and I believe there is not another run scheduled.
The 35s had promise but is nowhere as nice as the original. Seemingly the financial hp 12c
has been in continuous production for years, and on the shelf at local office supply
stores. The quality of the 12c is significantly better than the 15c limited edition. I am
hopeful they will offer an anniversary edition of the 34c.
I am unfamiliar with the 20b and 30b models. Thanks for the info, I will look at these
models.
I looked at the Swiss micro but I am fearful of it very small footprint.
Cheers.

Anyone have a WP 34S? Is $75 worth it for one already setup? Is it
possible to acquire or build your own programming cable to mod one
yourself?

Wow! I will give it a shot.

There's a homebrewed effort to produce a new calculator from the ground up
in the spirit of HP RPN calcs. There isn't much info publicly available,
but there is discussion and polls on design decisions at hpmuseum.org.
