I bought Berkeley Mono largely for that reason. First, it's a great font that I love using. Second, it's a passion project from a small shop that cares a whole awful lot for the work and doing it right.
Berkeley Mono looks good and fairly priced (for personal development), and I like that they offer both ligature and ligature-free versions. Might add to my collection.
I really wanted to pick it up, but it lacks a lot of Unicode symbols which for some is a bit of a joke since they come in ‘ligature’ form.
