I think ours in an Emerson, I think we bought it at Target about 8 years ago, I think I paid about $99 for it, and it's still working fine.
The only problem I have had with it is that the water inlet line clogged up once. I had to remove the cover to clear it out. However, in retrospect, that was my fault. I was dumping the ice in our cooler and then reusing the cold, cooler water in the ice maker (since it was already cold, it helped the ice maker work better). However, there were bits of paper labels and things in that water and they ultimately clogged things up. So, I don't do that anymore! :)
I think most of them are the same underneath the case.
