I also had the fp430 which is the smallest they make, its metal all around and weighs about 60 pounds, it was large and heavy to move around. But its a good solid fridge. Never had problems with it.
I measure the power use when set to 40 degrees, it used about 25 amps in a 24 hour period. About average for those types of fridges.
If I had to buy another fridge I might get something lighter.
