Need suggestion on decent wireless adapters for desktop. USB/PCI

[IVNP]

Hi, I'm pretty much clueless with the desktop side. Have no idea which brands and models are good. Also good value. USB is alot easier to work with right? Just plug in and play. Speed wise, normal G standard would be good enough. Would be even better if someone can point out any deals on them or selling them.^^ Need to get two or three of them. Thanks in advance.
