I'm a bit surprised the article didn't get into what kind of mic too. It's not just about the quality, there are specific favourites of broadcasters that have a particularly nice proximity effect, the phenomenon by which some mics make one sound bassier when speaking very closely to them. This sound has come to be associated with trustworthiness and so on. So yeah, more expensive is not necessarily better - a wide diaphragm condensor in an untreated lively room is going to sound less authoritative than a cheaper but decent dynamic mic dead close. An affordable mic that sounds really good for this is the Seinheisser e935. It's not as heinously directional and tight as an SM57 so doesn't ding you when you move, but still has a nice close, warm proximity effect. I use it for zooming and I have much more expensive mics on hand. A more expensive broadcast favourite with a milder proximity effect is the Electro-Voice RE20. Killer live mic too. Also - pop shields are good.
