Bought a used bread slicer from a diner closing down three years ago. Thing weighs like 400 pounds and the blade guard is held on with zip ties but it cuts perfect every time. My neighbor got a brand new home model for Christmas and it broke after two months. There's this whole parallel economy of commercial gear that regular people never see. Refrigerators meant to run 24/7 for a decade vs. the shiny one at Best Buy that dies right after the warranty.
Yo man that's the thing nobody talks about. The commercial stuff is built for abuse, not for looks. That ice machine probably has a real compressor, real copper lines, real insulation. The home Depot special uses a tiny rotary compressor and plastic parts that crack in two years. I fixed a commercial ice machine once, everything was serviceable with standard tools. Try fixing a modern home ice maker, good luck, you're throwing the whole thing out. That $800 is cheap for years of reliability, bet it churns out ice like a monster.
