Product review (2 stars): Disappointed that something so simple has been so difficult
Update:  After trying for 6 months, I still cannot simply tap a keg and enjoy the beer.  This has been a very frustrating experience for me since the first issue with the regulator (described below).  I regularly blow through CO2 and every time I need to refill the CO2 tank I have to drive 45m to the local brew store.  I have checked for leaks 10 times, tightened every connection possible.  I replaced all of the hoses (which helped with over-foaming..I thought).  I replaced the faucet, thinking that this was the cause of the leak.  Now the issue is that when I tap the keg and ever so slightly open up the CO2, it way-out carbonates the keg (so the foam is likely from a bad regulator and not the hoses).  My only recourse is to vent the CO2 out of the keg (which then prevents it from pouring).  I have ordered a new regulator; hopefully this fixes the issue of the keg getting over-carbonated.  So net-net, Ive spent $60 in CO2 for 2 kegs worth of beer, $50 for a new regulator, and $30 for new hoses etc.  And I still have the issue that with my new hose set-up, the Sankay tap and hoses are too tall to fit into the kegerator standing upright.  I'll probably end up selling this one.

I debated a 2 tap; 3 tap, under counter, larger system....varying from $400 to $2000....but ultimately I decided on this one because of price.  I picked this up for a great price on amazon with no shipping or sales tax.  My wife made a good point that with only one beer drinker in the house, what am I going to do with two taps (plus I could always change it out if I really needed two beers on tap).  And the counter-mount idea is a few years off for us (remodeling the basement).  And this one comes with a sankay tap which is worth another $25.  So this is a great starter kegerator.
It will only fit one 1/6th keg (5 gal) that you get from your local micro-brewery but it will fit 2 homebrew-type kegs (Cornys).
It comes with a 2.5lb CO2 tank - which is fine for one keg.
The instructions are a bit involved if you're not an experienced kegger.  For example, when I hooked up the regulator to the CO2 and opened up the valve, the CO2 shot out the pressure release valve.  I called nostalgia and connected straight to a woman who explained to me to turn the red knob all the way down and then to turn on the CO2.  This process somehow reset the release valve and everything is good to go.
Also, another tip - when tapping your first sankay keg, make sure the sankay tap is up first, then you easily twist it on, and then you press down.  This prevents beer from spraying all over you.
Overall, Im happy with it.
