Our fridge is similar to the one I linked to except it's half fridge, half freezer, no water cooler or ice maker. Totally sufficient for our needs till we started rearing our own meat when we invested in a chest freezer (you can fit a whole Hereford and 2 lambs in ours).

How big a family do you need to make such a huge appliance worthwhile? Having said that in the new house we'll be going for a fridge like that in the linky plus a half height freezer, which I guess won't be far off the capacity? We'll be choosing our appliances mostly based on energy consumption.
