After reading a review on MacZealots, I decided to try WiFind and ended up buying it.
WiFind is simple and very useful. It replaces the Airport status menu with a more informative menu telling whether each network is open or protected and the signal strength. It came in very handy at WWDC and is well worth the $8 price.
Glad you found the review useful. I'm always paranoid that I'm just retreading on old territory with reviews. 🙂
