Now that there are some experienced appliance purchasers on the thread, I'd like a word of advice on rice cookers. I once was gifted a new one which had been a wedding present but the bride did not like the aluminum bucket in which the rice was boiled. I am materials conscious but I did not see how mere hot water could leech anything out of aluminum provided I used the appliance just for cooking. It sure was convenient. Now that cooker is long gone and most new ones seem to be aluminum as well. Any reason I should stay away from them?
