Ok so I bought an iMac G3 for a little more than I wanted to originally but I really wanted one. I'm going to put it in my room and stream music to it and I need a way to get wireless, like the cheapest possible way. Its running tiger. Is there one you guys recommend for it? I know that the original airport cards are on Amazon for like $15 but I really don't know if that is better than USB. I would figure that USB 1.1 would have some impact on internet performance.
