That's one of the cons for the Nissin. Though I read in a review that the 1/32 power can be further reduced from the camera menu via FEC. Not sure if I understood that right.
1/32 is it, it does not go any lower in manual. This is straight from nissin's site "The power level is provided from full power (G.No.44) down to 1/32nd power in 1.0Ev increments." So in manual you do not even get the third or half stops like you do with other flashes.

Yep. I think I can live without that though. If I shoot wireless, I'm likely to do so at home/indoor, using my umbrella, and therefore manual usage is fine.
If thats the case then then the yn468ex II is a great choice. Its not as powerful as the 430ex II but it is small and light. I've had a yn468ex for a couple years, actually my friend owns it now, but it has never once failed in the approximately 2 years that myself and my friend have been using it.

I read similar stories of flash dying when fired at full power. I have to admit I do not feel very confident buying a YN after reading so many mixed reviews. YN also seems to come up with new version of their flash continuously, which give me the impression none of their offers are that good if they feel the need to continuously upgrade their models...
Don't get me wrong, the early yn565ex's were utter crap! I when through two of them, both had the main board issues that would only fire the flash at full power while in ettl mode (it wasn't that it died when shooting at full power, just all ettl would do was fire and full power. Manual setting would still work fine though). Like I said this issue has since been fixed. The yn565ex has a thread here in the flash forum and since yongnuo fixed the board issues there have been no reported issues in there. I think the date code that is needed to be sure it's a fixed flash is 10/2011....you'll want to double check on that though, it may be 11/2011.

Yep, it's a great flash on paper. Just like most of their offerings: feature packed and inexpensive. I'm just having doubt about the quality. I'm not in a rush to buy a new speedlight (I plan to take "advantage" of my broken 430ex to learn manual flash), so I'll keep my options open. Will read more recent YN reviews to see if the quality improved.
The yn568ex also has its own thread here in the flash forum. Like I said the only issue that has been noted is its over exposure in HSS with a SS of 1/250 on some cameras. A side from that there have ben no other issues noted, and lets be honest, this is the internet; People are more likely to complain about something that went wrong then to praise something for not breaking. So the fact that there have been nearly no complaints about the flash should speak volumes.
Yongnuo has really been upping their QC. Is there QC to canon standards? No, but there is only so much you can expect when a product is half or a third the price. I don't know what prices are like in Malaysia but here in the US the di622ex II is about $85 more then a yn565ex and about $140 more then a yn468ex II. So I could almost get a 565ex and a 468ex II for the same price as one 622ex II or I could get two 468ex II and still have some money left over. Like I said though, thats for me here in the US, the price difference in Malaysia might be closer
All are going to be good flashes.
The di622ex II is going to be the most powerful (its 1/10 a stop more powerfull then the yn565ex and 1 and 7/10's more powerful then the yn468 II), and comes with the longer warrenty for you. But it's the most expensive of the options you listed, is limited when it comes to manual power control and has a limited FEC range in ettl.
The yn565ex is nearly the same power as the di622ex II, is cheaper, has the battery pack port, has a wider range of manual control's, and has a wider range of FEC in ettl. But it has a bad rep due to the main board issues with the early models.
The yn468 II is the cheapest of the options you listed, has a wider range of manual setting, has a wider range of FEC in ettl mode, is small and light. But It is the least powerful of the options and doesn't offer ettl slave capabilities
speedlights.net
has review's for the di622ex II. yn565ex, and yn468ex (mark I more mark II, but only thing that changed was the battery door and pc sync port)
