Which card is good?

[Ben]

Hi all,
I'm going to get a wireless nic at the computer fair this weekend, and 
would like some recommendations.  I want one that works well with linux, 
and hope to join up on air.net.au if there is coverage in my area 
(Griffith/Narrabundah).  I was thinking of the d-link dwl-520, is it 
compatible with the air.net.au network?  What other cards might fit the 
criteria?

Thanks in advance,
