Use an FM or TV tuner and use the white noise for entropy. I'd trust that.

Really? That noise is often fearfully non-random and highly correlated, and anyone with a radio transmitter or indeed any electrical device can introduce new patterning. It's... not a good noise source on its own (though obviously it contains noise, so it could probably contribute *some* entropy.)
