Ok, I have bought an old ibook G3 clamshell off ebay, and I want to make it wireless. I have considered getting an AirPort card, except they are about 50 plus, which is more than I paid for the laptop. Are these cheap USB memory stick style wireless things any good, or are they ineffective? Are there any good airport "replicas" as such, that would work in the laptop?

Thanks. any advice will be appreciated
