As an RPN aficionado you should consider building yourself a WP 34S. We've put in all what we could do to make RPN programming a pleasure - think of local registers and flags, keyboard access, flash libraries, etc. Calling it "a nice little capable machine" has some understatement in it.

DIY is far more rewarding than buying one pre-made or second hand, You just need some manual skills if you want to add the chrystal and IR functions.

And Walter's manual is a work of art on its own. Not free but worth every € cent it costs.
