Cardbus Recomendation

[Quantum Scientific]

My Orinoco Classic has gone deaf, so I need a new adapter that will work in monitor mode (Debian Sarge), and which has an external antenna plug.

The website seems to be a bit out of date, as it recommends Orinoco and Cisco.  Most Orinocos these days are used, and a new one fails after 2-3 years, so I don't want a used one.

I haven't found any adapters with the new Atheros 6000 chipset.  The Belkin/Netgear IMO cards work great, but:
- No Linux driver;
- No monitor mode;
- External antenna would be problematic.

What would be the most sensitive and most powerful adapter these days, which can do monitor mode, and has an external antenna plug?

Best,

Carl
