I am looking for a good microphone on sale black friday my budget is 300$. I want a really good microphone any suggestions

I hear condenser microphones are the best for vocals. Look on amazon and view ratings. I'm possibly looking into get a different microphone myself. 

any brands

I highly recommend you try out mics before you buy! If you have a music shop near you, especially a larger one like "Guitar Center", you can call and ask to test some of their microphones in the store. That way, you're saved the hassle of buying and returning mics. I started with an MXL 990 that I liked a lot (I see it's currently $99.95 from Guitar Center), but because each voice is different, you might prefer the sound of a different mic with your voice. I tested several mics before landing on my current one (from Vanguard Audio Labs), and it was very interesting to hear each mic with my voice!
