Hardware

I want to run Monowall on a thin client computer, which only has one NIC and no PCIs so I need an adapter for usb.
Unfortunately the adapters listed on the FreeBSD hardware support site are so outdated that I can't buy them anymore.
Does anyone know a working adapter that is currently available?
The hardware notes from FreeBSD 6.2 state that these devices are supported:
