Need help finding a 48x24x24 glass terrarium

[slowhite03]

So let me just get this on the record before it gets out of control. I don't want a sliding door or a anything like that, thought I did but now I don't. Ok now here's my question, does anybody know where I can find/order a glass terrarium in a 48x24x24 with a locking lid? I know zilla makes one but I can't find those anywhere and none of my reptile stores has any, they just have a 40 gallon which I currently have. Any help would be greatly appreciated
