Ok then. It's decided. By next week I'll have a tub all ready to go.

Iris CB-70 tub
Exo-Terra UTH (16W, ~11"x11") under the warm side; thermostat controlled
Nothing under the cool side

And the usual bowl, hides and whatnot inside. I guess if it doesn't heat the cool side up enough I can buy another UTH.

Do I need clips or something or is the lid of this tub secure enough?
