Protein Powder

I ordered my first container of protein powder last night. Shelly at theworldaccordingtoeggface.blogspot.com believes that Max Protein Powder is the best, so I'll give it a whirl. I'm super excited!
I don't know if I could have ordered it at a better time. I just love hot cocoa with all this cold weather, but there is absolutely nothing nutritional about the stuff. It's just calories, but if I can make hot cocoa with the protein powder I'll get getting loads of protein.

What protein powders do you recommend?
