A lot of people have been asking how powerful the YN560 is w.r.t the 430ExII so did some quick test.
Sorry for the eyesore scene, but I went down and dirty and just pulled the car out of the garage to make some room.
These were taken in the dark at 1/200, F/11, ISO100. Converted from RAW to JPEG in DPP without adjusting anything.

I think it's clear who the winner is. The 430EXII seems to be brighter (I don't have a lightmeter so don't really know exactly how much, but from the samples above, seems like 2/3rds to a whole stop. But the shots at 105mm show the 560 is brighter at the center.
All the photos were taken on tripod with the 18-55IS at 18mm.
My impressions: The buttons on the YN560 are very convenient and allow quick changing of settings. The built of the body is similar to the 430EXII with really good quality. The bad quality feel comes once you look into the flash head, especially if while the head is zooming in or out.
Great recycle time, really nice slave modes (one of them to handle pre-flash from other sources).
YN560:
Pros: A lot of features
+ it tilts down unlike the 430EXII.
+ Built in slave.
+ Great build quality.
+ I paid $77 only.
Cons:
- Zoom head seems fragile, although I'm only talkign about the feel, who knows how durable it might be.
- Not as powerful as expected.





hehehhe maybe you can find the trimmer and adj it to produce more power? as it has very very fast charging... probably short changing the capacitor for the recycle times? it seems too fast for the supposed rated GN.
