I just got my Nautilus in today, and it is Pyrex. I would be interested in a wire cage to cover the glass, kind of like an old industrial light bulb cage, if they were to make one. 28 years as a tool and die maker has caused me to enjoy industrial looking things...and it would be cool if they were available. Until then, I've ordered a cut stainless tank for it. It should be here next week.
