If possible, I'd go for a regular AirPort card and skip the USB dongle. Airport works effortlessly and at least here in the States, they have gotten really cheap over the past year os so. I have purchased 3 original AirPort cards this year, and never paid more than $20 combined for card + shipping. The last one I got for $9.85 shipped. Also, if you're going to run Tiger, max out the RAM. My 366MHz indigo struggles with Tiger and 576MB of RAM installed. I just have 10.3.9 on my Graphite 366 with 320MB and left my 300MHz Blueberry at OS 9.2.2
