Thanks to the Real Food Summit I found a raw, grass-fed whey protein powder. Has anyone here come across this? Tried it? What do you think of it?

You can learn more about it at the following 2 links:

I haven't enjoyed whey protein all year but do love smoothies with them. I think I might try this although its very expensive. Do you think it's worth the cost?
