Circumstances where a user is adding a list of items to a page and hitting save then adding another. Where would the user expect to see items saved prior? Is it above the "add another" button or below?
It's kind of tricky to answer, since there are both options "out there". But the one I see the most are either above or to the right - seldom at the bottom. The reason I think is other controls such as a text input field where you expect feedback above the text, rather than below. To be consistent with that - keep feedback on the same place throughout your application.
So there's two issues you're trying to address:
Issue 2: Where you put the controls depend on the number of items in the collection.
If the number of items in the collection is small, it shouldn't matter if it's consistent at the top or bottom. If you expect there to be a ton of information, then it is worth repeating at the top AND bottom (except in the no data scenario--having 2 sets of the same controls with no content in between will like a mistake):
