You might see if you can get some Brown Cow brand. I know it's made in California, but I can get it at Whole Foods here in Atlanta. They make a low fat version as well as the cream top. If you buy plain, you can sweeten it with Splenda.
My daughter, who is also very persnickety about the way food tastes, says she likes the Yoplait ultra. It's sugar free, supposedly has a great taste and texture.
