Rode Podmic is about the best you can get for under $100. BUT, it would require an audio interface that can take an XLR connection. Blue Yeti is about the best bang for your buck for a USB mic.My birthday is in about 12 days now and I'm really wanting a mic so I can talk when I screen record videos with people actually being able to hear what I say. Partly why I haven't talked in my videos cause I don't have a mic that's not built into something else like my phone or computer, and the other part is just being a bit nervous that people will make fun of my voice. So I wanna try and ask for a mic for one of my birthday gifts so that my voice would at least (hopefully) sound better when it's being recorded, but I need options that aren't super expensive.
If you have a used music equipment store, you can probably get a steal on a good used mic and even an audio interface. Pro equipment is generally built to last, so buying used isn't a bad option.
