adsl modem recommendations?

[Roger Searle]

Hi, I have discovered today that my local phone exchange box thing now 
supports adsl (actually it has for the last 6 months).  I am just 
waiting for confirmation of available capacity from that cabinet (it has 
been fully subscribed in the past prior to the recent addition of a new 
"bit" and there is the possibility of this too being full).  The usb 
modem given away by telstra clear doesn't support linux so I'm in the 
market for one.  Does anyone have recommendations for good makes and 
models?  Or ones to stay away from?   Probably with 4 ethernet ports so 
I can plug it into my now full 5 port switch.  Linux friendly of course.

Cheers,
Roger
