Need wireless network card for my new dell dimension 4550

[Goopster]

Can someone tell me which one is good, cheap and easy to use?
I have a linksys wireless router and one of my computer has netgear's wireless network card.
I am thinking USB, are they any better than regular PCI's?

Technology wise PCI card is probably slightly better then the USB.

However Wireless is depending on signal propagation.

For Desktop (or tower case
) USB Wireless Client Card should be considered as the preferred solution.

PCI Wireless Client Card ends up been stuck behind the computer's case, resultant in obstructed transmission and poor performance. USB is connected to the Port with 2-3' cable allowing the Antenna to be placed above the System for better Transmission.
