Some are even cheaper than that now. Sliderules were good, but precision dropped precipitously as the number of significant digits rose.

I had the very same experience. I was a TA in the Psych department for a while. One of my tasks was to grade papers in a class that used statistics, among other things. I was given this TI calculator with all those little metal strips in order to perform the calculations. At this late date I couldn't begin to tell you how it worked or what calculations I actually performed! lol

I still have my slide rule from high school. I doubt that I remember how to use it. What a simple, wonderful tool. I remember that the early TIs cost about $450 and were the size of small bricks. My favorite calculator has always been the HP12C. I bought one in 1981 for about $95. It survived 25 years of hard use before passing on earlier this year. When I bought a new one for $75, the clerk asked me if I wanted to buy a one year warranty. I couldn't help myself from laughing out loud.
