Yeah, I just like the glass cuz it's easy to flip open the top...and I've got some jumpers. Egg crate is good- especially if you're outfitting an entire fish room, but the glass is more aesthetically pleasing.
You can get them online, or pretty much at any LFS. I believe Perfect0, All-Glass Aquarium and just about every brand makes 'em. They all fit standard aquarium sizes, although my Marineland one is a bit tiny for an All-Glass Aquarium I have, I'm the only one who would notice that. They come with a little plastic strip on the back 1.5 inches which you can take off, or cut so that the filter, etc fit into the tank and you have the most coverage possible.
