wireless card and antenna

I wanna buy a wireless network card for my laptop, but I don't know what kind I should get.  It's going to be used exclusively for stealing other people's internets.  I was thinking that I should get one that you can hook an antenna up to.

I know nothing about wireless cards or antennas.  What kind should I get?

I would recommend going with a lynksys they are pretty desent and affordable but also make sure that it has a range extender ability. that is just my opinion you might also take a look at the  usb wireless cards they are pretty inexpensive but are actually kinda decient for the price. well that is my opinion.
