I bought a mic from this site called
Shortcut Editing Keyboards, Vocal Booths, USB Studio Microphones, Pro Tools Keyboard, Final Cut Keyboard, Avid Keyboard, Adobe Premiere Keyboard, Pop Filters and much more, have been using it constantly since and its actually amazing, I get perfect vocal recordings every time! Is nice and crisp on its own but also picks up the sound from my guitar really well. I bought the SL300 but they have a cheaper one as well, probably just as good!
Also just bought a pop filter from them too, pretty cheap and works really well with the mic.
Definitely give them a go.
