I have HP 50g too, this is more complicated calculator with huge number of functions. It's very interesting to calculate with 50g, but for quick calculations I prefer HP 35s.

Except for the keyboard. I had a 35s for a year and the plus key is no longer responsive every other key press. 35s is no longer reliable and taking dust.

But what non-vintage RPN calculators do have a nice keyboard?
