Bunn is teh awesum for industrial coffee makers. We have one piped into the building water line in one of our conference/class rooms (with inline filter), and it's the bomb. It heats up the water to just below boiling - I think the setting is 205F, according to the LCD screen - and it'll brew a full pot in like 3 minutes. It's a glass-carafe-plus-warmer model, but it's been well attended, so it's never burned a half-cup of coffee into sludge on us.
The kitchen coffee maker is a no-name Nr. Coffee knockoff, not NEARLY as good. Not piped into the wall, doesn't heat the water enough, and still a glass-carafe-plus-warmer model, which people WILL ignore and create sludge from that last half-cup.
