Hey this is a newbie question but here goes. I am attempting to build a kegerator from an old fridge. It is a standard fridge freezer not a mini fridge. I would like to have two taps on it. I have been looking online at conversion kits and it seems that for everything i need the best deal is http://stores.kegconnection.com/Detail.bok?no=330 but i also found this for 10 bucks more but can figure out the difference http://stores.kegconnection.com/Detail.bok?no=47. So my two questions are what is the difference and am i over paying for the conversion kits? I don't have any kegs, co2 or co2 regulator. Thanks
