I've been using and baking with sourdough for about 6 months now. I love it. I haven't perfected the breadmaking from straight up sourdough yet, but I'm very close and I'm not unhappy with the results I have had. A little more tweaking here and there and I'll be feeling fully confident. I've made several loaves with just sourdough, which is time consuming. I've also made loaves with both yeast and the starter (guaranteed rise yet still enhanced health benefits of sourdough) and I have made sweet breads, cookies and cakes with my sourdough starter. All in all it's a fun process and the taste results have been excellent.
I ran into this blog explaining the health benefits while searching around for some muffin recipes. It's worth a look and understanding that perhaps you will want to start a "starter" of your own!
