Id look into buying a Yongnuo 565ex
I looked into Yongnuo and Neewer flash, and it turn out that they over rated their guide number. At best the Yongnuo and Neewer flash actual guide number are just slightly above the 430EX II Speedlite in TLL mode and match the Speedlite in manual mode, which is well short of manufacture rated guide number. Hence it make sense for me to get a used flash that give me a bit more power at roughly the same price as the Youngnuo.

I picked up the Speedlite an hour ago, and I disassembled and found out the only problem was the broken $16 diffusor lens. It will be an easy fix, but I will not be putting the weather seal striping back around the front fresnel lens because it is a pain in the arse to put it on the fresnel.
There are some cosmetic scuff and tape marks on the cover. I can replace the cover at the same time as the diffusor for around $65. But, I'm too cheap I will be replacing only the diffusor.
