We have an small Igloo Ice Machine, and we just love it ! This little ice maker fits on a counter top, and just keeps on cranking out little ice cubes. You can choose from two sizes of ice cubes, and the first batch will be ready in just minutes. When the cooler is full of ice, then the ice maker has a sensor, and it will stop making ice, so you never have to worry about the ice machine being over full. It can make over 25 lbs of ice in a day, and will save you from having to be making ice cubes all of the time.
We use a lot of ice, especially in the summer, so I was continually making trays of ice cubes. After we bought this for $89 at Sam's Club, we always had all of the ice we needed. It doesn't take up much space, and is simple to use, and comes in several colors.
We refill ours from filtered water; but you could also use bottled water or just plain tap water.
The only thing that I would like to see different is for the tray that stores ice to also keep it colder. Since the machine is not refrigerated anywhere but the actual part that makes ice, some of the ice cubes will ment as they sit in the ice tray. Of course, you could always store them in your freezer to keep them cold if you are not using them right away, and this is really not a big issue at all.
