I need information about corny kegs!!?

I am in the process of making a kegorator. I dont want to brew my own beer, i just want to have delicious ice cold beer always available. I like corny kegs cuz i can use a few of them, having more beer choices on tap instead of just one. So can i refill corny kegs. I like coors. I want coors! But dont want bottles or a huge keg. Anyone help!!!!
