Can anyone suggest. That's what you are trying to say, I guess.
It's hard to say really, without knowing how much you want to use flash and in what portrait situations. Others will be better placed to advise on specifics.
I have a D5000 with a Yongnuo 467. Really not a bad thing for the money. Maybe look at something like this and see whether it meets your needs before investing in something pricier. It would not go to waste - if you find yourself needing something with a higher specification, you will more than likely find a use for a second flash.
