My favorite is Optimum Nutrition ($50-55 for 5 lbs). Keep in mind that while that's a chunk of money to spend, it's going to give you 60-70 meals. You can find it in two lb cans, as well. I like to keep the vanilla flavor around to mix with berries, or cocoa powder, or peanut butter, or whatever. I also use it to make One-Minute-Muffins and pancakes... all kinds of stuff.
If you want chocolate, the best tasting I've found is Dymatize Fudge Brownie.
I usually buy mine at Vitacost.com, which is where I get pretty much all of my supplements.
If you always do what you've always done, you'll always get what you always got.
