Microphone for Youtube show

So i was thinking about starting a youtube show where i talk about things.

My question is, what's a good and cheap microphone i can buy? Do i need to buy a soundcard as well?



You can only get so cheap, I would look at the blue yeti/snowball or the AT2020.

All three are USB and won't need a sound card.

I agree with you on the Blue yeti.
