Product review (4 stars): Great Products for the Last 2 Years
I bought this as a 21st birthday present to myself.  For the last 3 years, I have put around 25-30 1/2 bbl kegs through this machine.  I have had some problems, but overall it has been an excellent experience.  Mr. Bird has made some good points against the nay-sayers of the 'rator.  I will give you my short run down.

+ Never frozen a keg.  Ever.  But I do live in Florida where inside temp can be comfortable at 76F
+ Wheels are nice for transportation
+ Produces some damn good tasting beer when cleaned enough
+ Foam issue is fixed quickly when you pour it properly: let the first 2 seconds out and then put your pint under
+ Come with all equipment, no regulators or tank to buy, mine came with a 5 pound tank
+ Very quiet and does not leak condensation, I keep it on carpet
+ Easy to disassemble and clean
+ Stainless steel look without the stainless cleaning hassle

= Does not accept Coors products, though I have found a few Coors kegs in a new rubber cylinder similar to Miller
= Does not fit all metal threaded handles, especially a beautiful Blue Moon one I got for my Bday, though plastic threads work
= Overflow container is a joke, but is easily replaced with a two gallon tupperwear container
= Can "only" get to about 37F, but is acceptable for even the crappiest light beer
= Wish it had a digital thermometer, like other models I have seen
= Did not come with a tank pressure gauge, only a regulated pressure gauge.  They are $5 from [...] and the regulator has an open slot for it.  Do make sure you get a left hand thread, as that was a huge headache for me

- Handle on tap can stick after a few days
- Faulty O ring on tap has wasted a few tanks of CO2, especially in the middle of a party
- CO2 tank is kept on the outside, I have seen models that can fit it on the inside.  The prevents it from sitting flush against the wall
- It was about $400 more than the exact same non-keg friendly fridge, seems a little extreme

If you are going to purchase something as cool as this, make sure you do your research on the model you are interested in.  If used properly, it can give you years of delicious, delicious beer.
