I've been having trouble finding metal halide lights where I live and so I was wondering if someone could give me the name of a mail-order supplier. I need about a 250(or higher) watt light over a ~100 gallon tank. Also, does anyone know how much this will cost because I really can't afford to spend that much. If its too much I guess I'll just stick with 200 watts of flourescent lights. :-) Roni Talukdar
