if your looking top up grade make sure its drilled!!!!!!!!!!!! every where has there own price because different company use different thickens of glass, so it might be cheep at one place but the glass might not be as thick... make sure you do some looking into and dont buy the cheepest tank cause in 3 years when you have your saltwater tank set up just the way you have always wanted it..... it might be time to reseal it ...id go for the thickest glass with reason for the best price.
