Wireless for my G4

just looking for a wireless card (airport extreme? or either a USB or pci version) for my G4 i'm currently using a 500mhz DP with tiger 10.4.1 and was wondering what route i should go? i plan on using my 1.25 DP MDD soon as i get more memory for it(in the mail) i'd like to get the airport card but i don't konw which one i should get. i want to hook up to my wireless network with 802.11g speed. i checked this site's market place but can't find what i need. if anyone knows where i can get one or that has one for sale, i'd buy it. thanks for any help

thanks matt
i did find this one on ebay "BUFFALO BROADCOM 54G 802.11B-G WIRELESS MINI PCI CARD" but that's a mini pci card? will that fit?

thanks again. this is the one i decided to go with > Here <. it's a usb type as i hope to buy a pci usb card with internal slots so i can put that in there and use the the internal antenna for the airport card. hope my plan works lol.
