Product review (5 stars): waaaay better than the nostalgia ones for the price
I also have a Nostalgia 5.1 cu foot one.  Imho it is a piece of crap compared to this.  When i got it, it was 300 bucks, but now that the price has gone up, it becomes a far worse value.  DON"T GET IT!  GET THIS!!!  The pushbutton digital readout on the front is great.  just push the up or down button to change your setpoint. It even has a quick chill button to cool it of quickly when you first change out kegs, and it gets warm inside. It does NOT read the actual internal temp on the display.  Just get an outside thermometer, such as for a car that is battery powered, and put the temp thing inside.  This comes with everything you need.  ESPECIALLY a 5 lb tank.  The Nostalgia comes with a 2.5lb tank, which costs me just as much to get filled.  I've just set it up and poured my first beers.  Just make sure your connections are tight, and be patient setting the regulator, and you will be fine.
