moved this from diet forum: casein help

The casein shake that i have been taking is pretty much just a scoop of whey and skim milk. Ive been searching around for the best casein protein and would appreciate some help in finding the best bc I dont really like to use milk.
I have found the Micellar Casein on www.proteinfactory.com, but that seems to be a little sketchy to me bc they claim to be the only people selling the stuff...why would that be?
Any suggestions about how to make this night time shake better with a casein powder would be terrific.

This is and edit of everything above...
I just found this stuff called component protein, here is a link http://www.bulknutrition.com/?products_id=515 what do you all think
