Many audio interfaces also work just fine with Linux OOTB despite there being no official support. While for microphones (and other audio equipment) there's almost no limit to how expensive you can go, any halfway decent USB microphone should probably be good enough that you're bottlenecked by the application's codec/bitrate. If you were willing to splurge a bit, you might look at the likes of the Blue Yeti, Rode NT-USB, AKG Lyra, Audio Technica AT2020 USB, or even Shure MV7 which range between $150 and $300.
