Thanks, folks.

I've decided to go with the glass, and I'll see about getting it coated.

Our beardie is NOT impressed with a glass enclosure. Or rather, with the other beardie that he sees in his reflection. I'm hoping that the new enclosure will be less stress for him. But, this new enclosure won't come until January, and he won't be moved into it until February at the earliest. I don't want to bounce him to a new enclosure too quickly, as he is suffering from some relocation stress right now.
