Best Prism3 USB Adapter for iBook Pro?

[AuDioFreaK39]

Hi, I was getting into WEP cracking on my mac this weekend, and I realized that I need to get an adapter with the Prism3 chipset in order to do so. The program I want to use is KisMac. Does anyone know if a Prism3 will work with it? Or do I need to get a Prism2 or 2.5? I want to get a USB adapter, not a PCMCIA card. Thanks in advance.

afaik, kismac only works with these chipsets:
Orinoco and PrismII chipsets, as well as older Cisco Aironet cards.

I run linux & use kismet, which is where kismac came from.
