Try Troegs Dream Weaver wheat. Best American Hefeweizen I have had. A lot of times the German one's we get over here are not very good with few exceptions.
I have made some absolutely killer homebrew versions before but have struggled making great commercial versions and I think open fermentation is the key here (not so much on 5-10 gallon batches though, sorry you aren't building up enough pressure to make a difference especially if you aren't using an air lock). Troegs uses open fermentation.
