Recommended new speakers for under $500?


Hi all, I'm looking for a set of new speakers for backup/second system. Anyone have any suggestions? I was thinking about the Usher S-520. I have no preference whether the speakers are full range, monitor, or planar.

The new issue of Stereophile had an excellent review of the Mordaunt-Short "Carnival" speakers. List price is only $250.00 a pair.
