This is a very intense mic! The ATR2500 USB microphone is one of the best out there.

For settings, I would suggest you put your recording levels to full, and keep your face about 8-10 inches from the mic. If you are using a Pop Filter, then keep your face about 5 inches from that, and the pop filter about another 5 inches from the actual mic.
This is a very durable mic, and you can find it here on amazon for $48: http://www.amazon.com/Audio-Technica-ATR2500-USB-Cardioid-Condenser-Microphone/dp/B004QJREXM/ref=sr_1_1?ie=UTF8&qid=1365288535&sr=8-1&keywords=Atr2500
