Hi, I want to start recording myself performing covers on youtube but I'm not sure what to do :S

I've heard you can either stick a mic next to your amp or connect your guitar directly to the pc. I'm thinking of getting a mic but I was hoping some of you could recommend me decent mics/webcams. I'm still fairly young but my b'day wasnt long ago so I have a fair bit of money.

Any other tips etc would also be very helpful.
