There's quite a few, actually. They're all commercial units that are expected to make hundreds of pots a day and stay cleanable and serviceable. Bunn, for example, makes a bunch of machines for which everything in the 'wet' service is stainless. By default they use a black plastic grounds holder but you can pay extra for a stainless one.
They're substantially more expensive than consumer units.
