Here's another option. Don't know anything about these but PSB is another "ex-NRC" brother to Axiom and Paradigm with some nice products.

Couldn't you just throw a nice tablecloth over the EP175 and put your drinks on it ? Nobody would have to know it was there... as long as they didn't notice the bubbles in their drinks
