I was thinking of getting a air port extreme card for my G5 (didnt get it when i orderd it). Now i need a wireless option to pick up a wifi connection. i was thinking of the AE card but was wondering if there was anything better out there. like an external antena like the ones linksys make for like 50 bucks. I want a strang signal and i just read the PB aluminum theory thread. So any suggestions? Thanks!
