ok, my question is do you want a top for the tank? or do you want a canopy?
for a top: glass is relatively inexpensive as are the little handles that you stick on with silicone. and my personal favorite is the light fixture egg crate.. a 2' x 4' piece is around $10 at home depot and you can cut it to fit your tank exactly with a pair of side cutters.
for a canopy: there is nearly nothing that is a less expensive alternative to a good hunk o hard wood. even the stain or sealant isn't very expensive.. just a couple good coats is all it takes.
