I am just about to order Starphire(all 4 sides) glass aquarium size 72X24X30 that is 3/4 inch thick. So far I have two quotes , one from glass cages and another one from coasttocoast aquarium. Glass cages is a bit short of 3k and coasttocoast aquarium is 3400 without packing or delivery cost. I did my research on the cost but I am still confused . Can someone PLEASE shed some light on the range that I am talking about. Are these numbers fair? Or is it too much for what it is worth?
