Advice Request Which calculator do you use?

[ttto]

I recently bought this one:
Amazon.com : Casio FX-991EX Engineering/Scientific Calculator, Black : Electronics

As a chemist, I found very useful its menu to access very fast to the statistic stuff, and its screen its fantastic for this kind of non-graphical calcs.

What's your preferences?

Considering I needed a graphical calculator for high school and uni, I purchased the Texas Ti-nSpire.
Great but extremely expensive for what it is... like all calculators.

I prefer to use the one simplest inside my brain, but i often use a TI-30 XS Multiview to calc sen, cos, tg, ln, log, e...
I like it, no charge...

I use Casio FX-CG20 for school. Do not like it much, though.

As I continue to use my old but impressive FX-880P.
I have it since I did the university for technical calculations (I did engineering) and still, 20 years later. Is still a portent !!!
