One of the reasons I chose the Canon S5is was that it had a flash shoe.

I'm leaning toward getting the Quantaray QF30 Flash over the Canon Speedlite 430 EX.
There is a $200 difference in price.
The big question is: What would justify spending $200 more for the Speedlite 430?
It seems the Sunpak has most of the speedlites features.

Well, it all depends what you want to do with this flash in the future. I would say for your S5is it's probably going to do the job quite well.

In my opinion it's a matter of upgrade that could be the problem. Will you one day buy a Canon digital SLR? Or do you want the flash to work on your S7is one day? Canon plays that game of changing things within their software, and then Quantaray, Sigma etc... equipment suddenly doesn't work on the newer cameras anymore. So you may have to buy a new Quantaray flash for your S7is. Maybe not. It's a gamble. Seeing that it's only around $100, it might be worth it though. Worse case scenario, you have to buy another $100 flash for the S7is, still cheaper than buying one 430EX.

My s5 and I are going to NY and wondering what your experience has been. Did you go with the speedlite or the other unit? How is your choice working out for you? Same question for anyone else in the forum...
