I just got one of the Danby kegerators with 2 faucet tower from a friend (good friend, it was only $50 including the CO2 and regulator!). I have to go through all the lines and a bunch of fittings to get rid of some nastiness. I've run kegs on CO2 for years, but I've never owned an actual kegerator. I have a beer fridge in the garage that can fit a keg and my CO2 inside, and I just use a faucet attached directly to the Sankey tap (in a round about way with ball lock fittings from my homebrew days). Since the whole thing is always cold, no foam.

But now with this new gadget of a kegerator with a tower, I'm sure I'll have a learning curve. Thanks for the heads up of the warm tower causing foam. I saw a tower blower yesterday on Amazon when I was checking out kegerator parts, but I thought to myself that there was no way I was going to spend $65 on something like that. After a quick Google just now, I found this and thought I might try it if I'm changing out lines anyway. He just ran the beer lines through a length of copper pipe into the tower to transfer the cold from below and insulated the tower. Seems like a good idea: http://www.homebrewtalk.com/showthread.php?t=43072
