This is the one we bought.

We were sceptical at first and read the pros and cons.
You have to be there to empty the "bin". It fills up in about 60 minutes. That is almost a gallon bag full. The ice is round hollow pellets. It is soft ice. We put the ice in our freezer then transfer to our coolers. If you're vigalent and keep attending to the ice machine (my job), you can fill a large cooler (Yeti) in a day.
We've stopped buying Ice at the grocery store. That's a savings of $4 every 4 days. How many times have you gone to the store just for Ice? Gas savings also.
We keep our Icemaker outside plugged into the side of the trailer. It is not rainproof but could survive a shower or two. In hot weather we use aluminized insulation cut for our skylights, to keep it out of the sun. That will make a big difference.
Would we buy it again? Yes.
