This may be a dumb question- but is it better to use a freezer or refrigerator as a kegerator? (Domestic beers only) I know 36-38 degrees is at the lower end of a refrigerator's cooling capability, but why buy a temperature regulator for $100 to keep a freezer at the same temp?
Is the regulator just for people that own a freezer instead of refrigerator and want to do a conversion?

Thanks
