Nancy's and Brown Cow are two I can usually find in health food stores. Look for those that say cream at the top. I think Trader Joe's even has its own brand that is cream at the top and a European style that is like another brand that I can't remember the name of. Also, if you have to get low fat yogurt, that's okay. You can always add cream or creme fraiche to it if you really need the extra fat. I've made my own yogurt at home and it seems it actually comes out better if I use 2% milk. Really the key to good yogurt is that the milk is good quality (not ultrapasturized crap) and the cultures are truly alive.
