Berkeley Mono was the first time I bought a font.

It's so good. Perfect even. And they have a really neat customization tool.

I've been using it for a few years now and they actually still occasionally release a new version of it. Haven't gotten tired of it yet.

The only complaint I have about it is that I had to do a hacky workaround to get my Nix setups to pull it in since it's proprietary.

I even forked their "Machine Report" tool (which presumes Debian) to make it work on Linux/NixOS by applying a "polyfill": https://github.com/pmarreck/usgc-machine-report-nixos-editio...
