Remember also that a radioactive source thats decaying fast enough to
put out 20,000 bits a second the way the RBG1210 can isn't something
you want to stand near.

I don't get this -- why is cost four times parts? Is that including
profit?

Also, shouldn't it just be possible to buy a couple of components and
do as well as the Newbridge Micro unit? It would seem that we should
be able to build something a lot cheaper than $52 if all we need is a
noise source that will make a line go high or low on a clock input...
