I've got an older Raritan unit. Second one on the boat in 36 years, so they hold up well. My only complaint is that at least for my older one, the startup surge is massive, so when on inverter power the compressor has a slight stutter at startup (and every light on the boat flickers a hair). It could be a bit better insulated for lower power consumption, but it otherwise works great.
If the unit won't be exposed to weather, a non-marine one should be fine. But pay attention to power use if you want to run it on inverter power. The ones that make ice, let it melt and keep recycling are much more power hungry than the units (like the marine ones) that are basically just the ice maker from a house freezer stuck into a dedicated tiny freezer.
Vitrifrigo makes a 12v unit as well as all of the 120v marine units out there. It doesn't make ice as fast and I've never seen one in person, but it's an option.
