cheers pasta..... going by that the smaller ones take 24 hours, the inbetween ones have to have a cord sticking out the freezer and takes longer to freeze than other ones and the more expensive ones are quick as hell but it says they are impractical in normal kitchens and some of them cant be moved without waiting for 12 hours as it upsets the coolant....... im sure mercia said she sat to make it so maybe she has something different (like a star trek food replicator)...wouldnt fancy one of those stuck on the kitchen table or on the edge of a worktop!
