There are many available. I have a commercial unit at my Lake Havasu house, where it will make about 75 pounds a day. These units must be cleaned often, you need a good filter, and a drain line is a must. Unless you are filling ice chests daily, it is almost cheaper just to get a new fridge with a new ice maker.
I use one as my water line to the fridge needs replaced. Something to consider is that they don't store ice well and the ice is only 32° rather than fridge freezer temp. I transfer mine to the fridge container but it clumps due to being wet when I dump it in.
