I have a top from Artfully Acrylic. You give them all your measurements and where you want to have cords, etc., and they make a custom top for you. Well worth the money and looks great.given how important it is to have a secure top, what do people do when they have an over the top return, an auto feeder, and wires that need to come from the tank? Are people able to make more custom tops that cut out the space needed?
