Combunctor is one, as well as Baggins (use Blizzard Skin in options) both look like Blizz frames but give you an "All-In-One" approach. As far as I know, Combunctor isn't Ace2 (but the author is testing on WoWAce) and Baggins is Ace2. Not that it should honestly make that big of a difference...they're both wonderful AddOns.
