What's the current go-to calculator for electrical engineers?

Hi fellow engineers,

having to replace my trusty old calculator, I am trying to find out what current models are good for daily use by EEs.
I don't have any restrictions on functionality as a student may have. What I'm looking for are features like:
 - Easy to access constants (light speed, Boltzmann, elementary charge etc.)
 - Engineering notation
 - log functions preferably directly accessible (without using shift key)
 - Multiple memory locations
 - reasonable battery life
 - obtainable as new unit - not something I have to hunt down at EvilBay.

Any input is appreciated.

casio fx991ex

HP 35s if you like to use RPN. Available at around $60 USD.

TimFox:
For those who prefer RPN (and for those who have never tried it), Swiss Micros has put out a modern line of calculators based on the older -hp- models.
They use modern hardware and batteries, and their newer models have excellent pushbutton switches.
For normal hand-held calculations, my current model is their DM41X.

log needs shift key on the hp35s (even if it's a very good calculator !)
I have one hp35s, one fx991ex, one ti84 and one casio fx-cp400
love all of them.
the fx991 is the one I use most often because it never has dead batteries !
