Product review (1 stars): Horrible Customer Service
I received this in March, in good condition.  As the earlier reviews note, the documentation is OK nowadays.  Set up worked fine, with the same problems with getting the tap in that others note.  But ultimately it was fine.

That said, after four weeks or so, and less than a half-keg (1/6 barrel), the CO2 tank mysteriously emptied entirely.  After re-filling, checking all connections, soapy water, etc.--it did the same thing.  So I sent an email through their cumbersome online system, which is designed to discourage support questions.

I received a non-helpful message back, saying to check my connections.

I was out of town for the next few months, so I just shut the system off.  A few weeks ago I read up on line, and checked the system by pressurizing it, then cutting off the tank pressure and closing the output valved to the keg.  Over a week or so, all the pressure in the regulator bled off.  So I concluded that the regulator was to blame.

I sent another email through the cumbersome online system.  I received an email back, inviting me to call them.  So I did.  Their response?  "It's over ninety days since you bought it, so you have to buy a new regulator."  When I pointed out that I had raised this problem within the ninety days, they demanded I prove it.  Of course, their online system doesn't copy you, so it's hard to prove.

Anyway, maybe for the price it's worth taking a risk on the obviously bargain-basement parts they use.  Your mileage may vary.

Update 8/8/2013:

This unit is now entirely broken.  It was unable to keep pressure, as noted above.  I replaced the regulator and tubing with third-party products, which fixed that problem.  However, the tap kept getting stuck in the closed position.  It just broke (admittedly, I was pushing pretty hard--but I shouldn't have to disassemble the unit to pour beer).  So pretty much nothing about this unit worked--though it did keep it cold enough, unlike some of the other reviews.

By the way, I have also discovered an unrelated problem with all these consumer units.  The tower itself is not cooled.  That means that the first glass of beer you pour after more than ten minutes or so is considerably warmer than the keg.  That means it is very foamy.  The next glass is fine, but this is apparently a well known problem.  Commercial and higher-end kegerators cool the tower up to the tap, avoiding this problem.  There are workarounds on the web (running a small fan to blow cold air into the tower, etc.), but they are pretty complicated.
