[Ti] Good 802.11G cards for the TiBook?

[Josh Zhixel]

Lately I've found myself hanging out at the library/coffee shops in town 
  for 'net access, and I'm a little underwhelmed by my TiBook's wifi 
reception. I could buy one of those external antennas to improve it, but 
I'm not really ecstatic about having one of those hanging off the back 
of my screen, plus I wouldn't mind having 802.11g support.

Does anyone have any recommendations for a decent 802.11g card that'll 
'just work' on OS X 10.4? I did some googling and came across the Asante 
AL5403-XG, but nobody seems to be selling them anymore.

Thanks,
Josh
