Something that works well for a long time, is good value, and is not a Cole & Mason. Have three C&Ms sat in the cupboard which have lost their grinding edge - basically don't work. One of these is less that a year old.
Last time I solved this problem, I gave up and bought a disposable one from the supermarket. They tend to last about 3-4 refills before wearing out, which is comparable to some of the cheesy ones, at a fraction of the price. I did get one where they'd nobbled it with a one-way screw thread, but that was easily defeated by tactical melting with the sacrificial soldering iron.
At some point last year I was tempted by an electric one in Aldi, for about a fiver. It's hardly a pinnacle of engineering, but it's still working well. The grinding surface is some sort of plastic, though, so I'm not too optimistic about its longevity. Sadly, barakta hates pepper, otherwise an electric pepper mill would count as a Reasonable Adjustment.
