Optimum Nutrition also makes a product called Pro Complex PM. It's a blend of casein, whey, and I think egg. I used both the chocolate and vanilla, and neither were too bad. I mixed them with skim milk. I figured the all casein stuff would be too clumpy.
I now usually use Labrada's ProV60, which is a blend of whey concentrate, egg, casein, and whey isolate.
Also, Iron Tek makes a blend with casein, and the Cookies and cream is actually really good. If I see the 5 pound jug of it on sale for $30 or less I get it. The Labrada is at The Vitamin Store this month for $28 for 3.5 lbs. It has 20 servings of 60 grams of protein. But I mix one scoop to get 40 servings, with 2 cups of skim milk , so each shake is about 45 grams.
I might try ordering Nitrean, from At Large.
I still use ON whey for post-workout, and sometimes in the morning or pre-workout.
But once during the day, and at night I take some of a blend, with skim milk.
