If you want a dynamic, the Sure SM58 is a good one (generally runs ~$100), or the AudioTechnica Pro 41 is another good one. You will also want to get an interface to control the gain and get a better analogue/digital conversion for the signal than what you can get from your computer. You can go cheap, like with the Behringer UM2, or more expensive with something like an Audient iD4, but if you go cheaper you might need to get a Cloudlifter to get high enough gain without adding hiss from the preamps into the signal.
