How do external flash Nissin di622 compares with Yongnuo yn465 for Nikon d60?

[Fatboy]

I'm an new to photography and bought nikon d60 few months back. I'm looking for an external flash with nice to have features. I have shortlisted Nissin di622 which is around $125 and Yongnuo yn465 which is around $70. One thing Yongnuo do not have is auto or power zoom. If I go with Yongnuo I would save some money; but will I loose something that is useful? Please help me, I'm struggling to make my choice here. Thanks for your help!
