We have one of those $99-150 ones that all look suspiciously like they come from the same factory, just dressed up differently. Ours is Magic Chef gotten from Home Depot on a Black Friday type sale. I like it and DW likes the ice. However it is fairly high maintenance. It works but is always out of water or full of ice or something. I shuffle the ice out of it to a container in the freezer, the big cooler, and cups regularly. Also refill it a few times a day. My wife has no interest in keeping up with all that. We are weekend type campers so I don't mind and just lump it in with the other camping type chores. But if we were full time I'm pretty sure I'd want one more automatic like in the house.
One downside with these is though they make ice and darn quick, they don't keep it. The ice reservoir isn't chilled. So not only will the ice slowly remelt, it's always "wet". So what I put in the freezer tends to freeze into a clump I have to break up later.
Another is that it's a bit noisy when dumping ice. I turn ours off at bedtime.
Last is it takes a fair amount of counter space. When needing to cook indoors it just has to go. Most of the time we don't so it's a small issue.
The amount of ice it makes keeps me and DW supplied pretty well when it's just us. However with a herd of grandkids it just lessens the need for bagged ice a bit I guess.
Not for everybody, I'm sure. I'm sure there are better ones but this one was cheap and does what it supposed to.
