Get the Texas Instruments TI-30X IIS 2-Line Scientific Calculator, Black with Blue Accents for $8.88. I have had this calculator for over a year and I love it. It gets lots of use.
From Amazon:
- Robust, professional grade scientific calculator
- It has 2-line display shows entry and calculated result at same time
- Easily handles 1 and 2 variable statistical calculations and three angle modes (degrees, radians, and grads) and scientific and engineering notation modes
- It has 1-year limited warranty
- The front of the calculator is black, the back cover is in fact a dark blue-gray.
