Just made a post praising this stuff in another thread; when I was on it I loved it. Tasted great, was a very effective weight gainer. I don't have the money to buy it consistently right now, but I'll be working more over the summer (I'm in college) and will definitely pick up 5lbs of it. I agree with Nelson about whole egg... a lot of proteins just use the egg white protein, which I don't quite understand.
In short, Big Blast = very tasty, effective, advanced stuff. Totally worth it if you have the $$
