Product review (5 stars): Very happy with this kegerator
We purchased the DKC645BLS-2 model from The Beverage Factory about 5 months ago. (That is the dual-tap kit, but it hardly affects day to day usage.) This unit is not perfect, but I would recommend it.

Easily stores two 5-gallon (sixth barrel) commercial kegs, which is exactly what I was looking for. Holds the two kegs and a 5 lb. CO2 tank comfortably. I think the unit is rated for three kegs, but I'm doubtful that you could actually fit a third in here.

Beer stays sufficiently cold. The temperature gauge only goes down to 36 degrees F, but that's just about ideal for our beer. The only drawback here is that the unit make take a while to get the beer down to temperature. A couple of new kegs arrived at about 60 F, and it took two days to get down to an ideal temperature. In the meantime, drafts were a little foamy. No complaints here, but keep in mind that some patience might be required.

The tower itself stays a little warm, so CO2 comes out of solution at the top of the lines. I have noticed that the first 4 oz or so pours pretty foamy, but then the rest of the pour is very smooth after the tower and faucet cool down. It's not really a problem, I just needed to adjust my expectations a little. The foam is perfectly drinkable when it settles after a few minutes.

Owning a kegerator and dispensing draft beer is a somewhat expensive proposition, but I have had fun monkeying with the CO2 levels, etc., it has become a little hobby. I'm very happy with the purchase.
