Beer Fridge Temperature Controller

Storing beer in a refrigerator? Any person using a temperature controller?
My BF is a beer enthusiast. He wanted to buy get a regular old bar and using a temperature controller ($ 60) with him to keep the temperature constant – The article says that is only as good as a wine fresh, but cheaper. I can not find much information about it, however. Has anyone done this? Do you know anything about this? (Actually, I found heavily on a cheap wine cooler, but have no temperature control of fantasy, so I guess that is not very different from a normal fridge) or any advice would be reported .. Great
can adjust the refrigerator temperature manually and just use a refrigerator thermometer to see if the correct temperature. any refrigerator will keep a constant temperature within reason, especially if you have a built-in tap water and did not open too. or, spend a lot of money in high technology crap1
