Best calculator for the working engineer

[inaqui76]

I´m a structural engineer, during my studies I used a 48gx after I graduate bought a 32sII and when the keyboard died switch to my old 48gx.
Last year I saw in a auction site (in Argentina) a used WP34s and it's been my primary calculator so far...
It is true that you use less the calculator and more the computer, so in my case any basic RPN it's a GO...

just my 2 cents
