Don't know where you checked, but I buy mine at Industrial Plastics. A large 4' X 8' sheet (I use 1/16" thickness lexan) is $90, and you can get smaller pieces. But I buy the whole sheet, as I use it for a lot of things. It is very easy to cut (use a tin snip), drill, form or shape. And you just need to bend a small flange if you want to stiffen up a long edge. I have made all kinds of things for my sump, incl a filter sock holder, and other stuff.

For a tank your size, it shouldn't cost you more than 30 bucks. Then you have a better top than anything you could make out of mesh or egg crate. Plus great light transmission, and reduced heat and water loss. And no more fish loss.
