I like Greek Gods or FAGE. Both of which I can find at City Market (another permutation of the Kroger stores) and at Natural Grocers (a vitamin cottage store).
Greek Gods is much more tangy and sharp, the FAGE is creamy, smooth and almost sweet. So 2 very different products! Brown Cow (City Market) is pretty tasty if you want a more 'regular' yogurt instead of greek yogurt.
But you do have to look around to find a source. My local independent market here in town (which I support minimally because the owner is a jerk and doesn't treat his employees very well) carries several brands of greek yogurt and EVERY one of them is low fat or non fat. Stupid world we live in.
And, if you don't find some or you want your usual store to carry it, ASK! If they get some requests they might actually start carrying it! And since yogurt keeps quite well long past it's expiration date you could ask them to order a case for you too. (And a lot of the time you can get a discount that way!)
