Agreed. Its even better if the homemade yogurt is strained. I got one of these a few months ago and have been mightily impressed.

I strain the yogurt down much thicker than even Greek yogurt sold in stores. It's great on a sandwich, as a mayo substitute, dressings etc. I have experimented with a number of different starters from commercial yogurts and each has a slightly different flavor. Homemade yogurt really is very good and worth a try.
