Top three calculators ?

[Helix]

I have already replied in this thread, but because I have more calculators now, here is my new top three:

1. HP 67 upgraded with Panamatik HC-67E ACT. I like very much the LED display, and the new ACT chip provides continuous memory, a convenient way to load and store programs (I'm not a fan of card readers), and several new and useful features. It's my first calculator for simple calculations.

2. HP 50g for more complex or serious tasks.

3. My other calculators are not for daily usage, but it could be the SHARP PC-E500S.
