Cheap Wireless PCI-E/USB card

Hello people of TekSyndicate.

My friend recently just built a computer, bit he wants wireless, which is not integrated on the z87 gryphon. So I wanted to get him a worked card for Christmas. Did anyone know a cheap ($10-$20) PCI-E/USB based works card that supports wireless n?

Buy him as much ethernet cable as you can afford. I assure you, he will be much happier.

He already has wired internet, but wanted wireless for some reason I didn't bother asking him for. And I promised him a wireless card.

This should be good and also has wireless n support.
