What is the best Fridge to buy..

Hi,

I am looking for a fridge to assist in the cooling of bars, moulded products etc.

The question I have, is what assets should the fridge have - what would be the ideal temperature of the fridge be, should the fridge have a dehumidifying ability etc.

I have read a post by clay where he says fridges are the one thing that most people get wrong when they start up, so it would be fantastic to hear about what exactly it is I should be looking for... would a regular under the counter fridge be suitable such as a Williams, Foster, Polar etc.? Such as the picture attached.

Thanks

George
