Compendium of Ten Key Calculators
Here's a list of ten key calculators by brand (in progress, best first, whatever after). These (sometimes called ten key adding machines) are generally of the desktop printing variety—because really how many ten key calculators aren't?—and include all the popular brands with links to the place where you can buy them. A list without links would be kind of stupid, and I like to think I've not been there in a while, or at least since my late twenties.

I'm just one person. Please don't assume I've used all these calculators, because that would be wrong.
