There are a ton! I'm a big fan of black flavored teas - here are some you'll probably like. Try Adagio's black coconut tea...it's simply wonderful - one of my favorites. A few others you might like are the (black) lemon and (black) apricot. All of these teas take sugar and creamer really well.
If you're looking for something less sweet, try Adagio's (black) forest berries or (black) Christmas blend.
Outside of Adagio, you should try The Republic of Tea
's black blends. I particularly like their Vanilla Almond, Blackberry Sage, and Cinnamon Plum.
Much more sophisticated in taste are the non-flavored black teas - there's something much more satisfying about a delicate Darjeeling or a nice malty Assam. Definitely consider giving these a try!
