It gives some pretty good pics and info about tub setup. It's not perfect, but should help.
As far as thermometers and humidity gages go -- most people on here agree that if it's not an accurite it is garbage. You can pick one up at WalMart for about 12 bucks.
Good luck!!
i dont know if i'm taking this a bit personal but what would you consider to be a "perfect" tub setup? thermo-hygro, uth, water dish, ventilation, thermostat, hide(s) and bedding are all you need for any setup.
