I HIGHLY recomment getting a chest freezer. You can pick up a used chest freezer and a dual keg system and a full keg for less than you can get one of these pre-manufactured kegerators. The chest freezers are the best. Setting up a kegerator is easy and fun, especially with a chest freezer. Just take a look at this picture to change your mind!
