Anyone using the free Tomato firmware with their router?

Is anyone running the Tomato firmware (or derivatives) on their router?

http://en.wikipedia.org/wiki/Tomato_%28firmware%29

1. Is there a best version? Most people seem to recommend TomatoUSB, Tomato RAF, Toastman, Shibby or Teaman.

2. TomatoUSB is probably fine but it has not been updated for over a year?

3. Does anyone know what BW Limiter or Guest SSID is on the feature chart?


TIA
