Rockband/Singstar mic works. They cost about 10-20$ depending on which type you buy 8D
They have really good quality too o/

I have a Samsung Go Mic. It's small, portable, uses USB to connect to your computer... Pretty clear when I record. Doesn't pick up bg noises, but I guess that really depends on your recording environment too. There's a port on the side of the mic where u can plug in your earphone/headphone to hear yourself. Helps a lot to improve singing when you can hear yourself~ But, of course...the price. It's under $50...depending on if you buy it online or at a retail store.
