Optimimum Nutrition makes a good product.
Keep in mind that the type of protein you should consume depends on the time of day. Whey digests fast- good in the morning to boost metabolism and post-workout.
Casein (egg protein) is a little slower- better to feed your body before bed (if you're trying to maintain muscle mass) or to hold you over in the afternoon until dinner.
