I'll bet the price quotes included polishing the edges. A pair of heavy gloves and a belt sander belt will take care of the sharp edges rapidly. The problem with buying glass at the lumber yards is that they don't normally carry 1/4" glass or acrylic. I use 1/4" acrylic for my baffles since it's thick enough to not bow under the water pressure. A good bead of silicon on each side will hold it in place for a long time.
