There are a number of meal replacement powders at some big chains (Krogers/Ralphs/King Soopers and Amazon at least):
"Raw Organic Meal" by Garden of Life
"All-in-One Nutritional Shake" by Vega One
I can't vouch for whether they "know what the hell they are doing" but I like the quality and really like the lack of sugar/carbs. A big problem though is they are low protein and calorie count so you still need to search for those.
But as a side note, and speaking for myself, I like Mealsquares better than any of the powders.
