Welcome to BP.net!
I urge you to take a closer look at tubs. When you start out with a tank, you lose most of your initial enclosure investment when you finally realize you should have gone with a tub in the first place. By the time you figure out for yourself why most experienced keepers are telling you to go with a tub, you won't be able to recoup the cost of the tank, screen top, stuck on UTH, and lamps. You will be able to use your hides, water bowl and thermostat.
