Usb / XLR microphone Quality ? price ? read my post for more info

Hey guys,

I'm a father of 2 young little girls and also a big gamer! so recently i've been able to come back into gaming but I'm facing a little issue.

I can play, but i am whispering to my teamates since my childs are sleeping and I'm freak and don't want to wake them up!

So. I'm looking for a mic that will catch my whisper. I have no problem using mic like NW-700 ( close to the mouth microphone )

I currently have an M-Audio Fast track for my guitar wich has a XLR and phantom so i guess i could use that for my voice when i'm gaming.

Well .. let me know if i'm out of bounds!
