These are clones of various older calculators.

I bought a DM42n last year. I didn't need it. I don't use it so often that I can justify its purchase. Still, wow, I do so enjoy working with it. It's one of those tools that just feels good to use.

There is a certain joy in working with RPN and in using a piece of technology that was designed as a tool, not as a toy or an educational appliance.

With phone emulation, I probably need half a calculator. I have three.

That's so true. It's custom-built to do exactly one thing, as efficiently and ergonomically as possible. I love any tool like that.
