Recommendation using Client side performance monitoring (boomerang/jiffy/episodes)

Question

There are a few Client-side JavaScript libraries that check web-site performance on the client side:

• Jiffy (http://code.google.com/p/jiffy-web/)
• Episodes (http://stevesouders.com/episodes/) by Steve Sounders
• Boomerang (http://yahoo.github.com/boomerang/doc/) by Yahoo!

Have you used any of them or a similar too?
What did you use for the server-side? for reporting?
Is this a recommended approach?
If not, how should I monitor my web-site performance from the end-user's view?
