Please, I'm begging you, go buy the casio fx-115ms instead.

Don't say I never gave you anything

For the price you can't beat the HP 9s Scientific Calculator.
It offers everything you need in a scientific calculator.

All you need in a 1-line scientific calculator [Posted on 2007-08-12]
After many years of relying on my HP graphing calculators (48SX), I had to scale down to a one-line calculator for use in one of my exams. HP sets the standard for engineering calculators. Unfortunately, the graphing calculators are a little too powerful for use in certain exams, since you can almost program them to do the work for you. My professor specified "1 line calculator ONLY" for the final exam. It's actually not that easy to find a good scientific calculator that's only 1-line. Most are 2-line, or graphing.

For a 1-line calculator, especially for the price, this one is perfect. It's not as small as I had envisioned, but that's because of all the features/functions they have to accommodate. And if you're used to using a larger HP scientific calculator, you'll find this one fairly easy to get used to (despite the lack of RPN date entry mode, due to 1-line limitation).
