I currently have plastic ones and I can't stand them! They are bowing and they just don't look as good as the ones that have a brace. I have glass on my other tanks and like the way it looks better.
The plastic one i have actually has a brace for the top built in its pretty much 2 singles together with bulit in brace connecting it. Definatly dont look as good as glass but its in my tankroom so i didnt worry too much about looks. Hope you get the glass to work, it should look good. Let us know how it trurs out.
