DES-Busting Screen Savers?

On the subject of choosing keys randomly, rather than dividing up the
keyspace... 

This seems like a very good idea to me.

One potential problem is actually choosing the random keys. Have to be
able to get entropy at a fast rate, and/or use a good PRNG. Both of these
things would take time away from the actuall cracking (more time than just
incrementing the key). And if a weak PRNG is used in order to save time,
it's possible that it might favour certain keys and thus interfere with 
the attempt.

Any ideas for a fast and good PRNG?
