if your looking for something reasonably priced with low power consumption buy a 3way and use it on gas,Had been using a chescold that was 20odd yrs old that died so we picked up a gasmate which works very well when the temp is below 35, anything above 35 we put the fridge into a thermo box ( made ourselves using a seafood transport container box thingy) which happily keeps the stuff inside around a constant 2-4 degrees.
9kg gas bottle sees around 25-27days of constant continuous use
