Haha...I might have to contact them and see if they'll custom-make coffee pots/makers. If they would it would be really expensive though!
You could take a large bowl that looks like a coffe pot, glue on a handle, make the "coffee maker" out of cheap bendable plastic and a wooden frame and put all your wiring and tubing in that. =] Then it'd look like a coffe maker and pot as a betta tank but you wouldn't have to custom order anything just to tear it apart afterwards! =]
