I bought Taam-Tov vegan creamer (you could buy it online at http://store.foodfightgrocery.com/index.html
.) I personally do not care for it. It's the usual white powder creamer, but without the dairy stuff in it.
One of my biggest obstacles in finding a substitute creamer, since going vegan, is that I like the 'thickening' action of creamer, not just the lightening effect. So, I was never a fan of dumping milk into my coffee (almond milk, soy milk, whatever).
But then I got to thinking about it - I like cappucino made with soy milk. Of course, in a cappucino, there's a lot more 'milk' than espresso. So, I've started adding a bigger portion of soy milk to my coffee - about 70% coffee, 30% soymilk. I think that tastes fine. (I think I would need to use even more almond milk, since that's a little thinner than soymilk.)
So, that's one alternative to consider - just use a lot more 'milk' than you're used to, and see how you like that. I also think this is good because I have cut down on the amount of coffee I'm drinking. That is, I drink the same amount of 'coffee' (I fill my thermos each morning, and that's my limit), but since there's more soymilk in there, I'm drinking less coffee. And I think that's good for me. (I already drink half regular/half decaf coffee, so this is just another way to help me drink less caffeine.)
