I loved calculators but I actually rarely need them. I've stopped buying them. But not before I bought too many.
The first calculator I bought was a used Sinclair. You, Stewart, will know of those. Amazing but very cheaply built. It didn't last and I no longer have it.
My first calculator was a Rapidman 800, which sold for about $100 at Eaton's, IIRC. My next one was a Novus Mathematician, which used RPN and then a couple of Sharp calculators, the first of which used batteries and the 2nd light powered. These days, I use an Android app called RealCalc. BTW, as I mentioned the other day, I still have a slide rule from my high school days. It's a Pickett Microline 120 and it still works 56 years later! By the time I got to Ryerson, I was using a calculator.
