Tempered glass is a fine covering. It is a little on the expensive side, but good. Regarding plexiglas and holes drilled in it near the edges, I found I had to drill a hole slightly oversized and then be extremely careful not to tighten the screw down too tight. As far as drilling goes, it's not a problem if you don't push too hard on the drill bit and you have a solid surface under the plexiglas. Any flex at all will cause problems. Can you tell me more about proper sharpening of drill bits for plastics? --Tom

I'm having trouble finding an apple to apples comparison of the polymers to tempered glass.

Plexiglass doesn't last long enough. I'm trying to pick Lexan or Tempered glass. Can't get straight apples to apples comparisons of price.
