Wireless Comparisons

[cbirds]

I am about ready to outfit my Ti with a newer 802.11g card, and many 
3rd party cards that fit into the slot have been recommended to me, 
some cheaper than Apples AP Extreme...which I assume would go inside 
just like the current AP card that  is in there now.

For the G4 which will act as the software router, is it better also to 
go with a 3rd party card or must I outfit that with AP Extreme since it 
fits INSIDE the computer?

I am not so much concerned with cost as with performance and user 
satisfaction.
Thanks
