This bloke is putting together a good quality, hardware RNG for ~$50 USD a pop, which leads me to a couple of observations.
The first is that a few of his RNGs would be a no-brainer purchase for anyone who is serious about crypto-based security. And secondly, I wonder how much it would add to the price of a CPU if someone the scale of Intel or AMD bought him out and gave away a hardware RNG dongle with every CPU sold.
