DM42 calculator from SwissMicros:

“The DM42, one of our line-up of flagship RPN calculators, is a true homage to the legendary HP-42S, widely regarded as the best calculator ever made. The DM42 is the most precise calculator on the worldwide market - second to none.”

I now favor that over my HP-35S.

Mitchums Anti Persperant. Works very well for hours. Widely available. Cheap.

Also the Philips One Blade shaver. Again, cheap, reliable, easy to use.
