Ok, I live in Michigan, so we are humid as hell in summer, but then there is winter... snow, snow, and more snow (especially in Kalamazoo where I will be). I will have everything regulated on a thermostat with a thermometer for monitoring and a temp gun for spot checking. The smaller of the UTH's already comes with the tank. The second UTH (the one I have to buy regardless because the small is too small) would be regulating my warm side.

The reason I ask is because the person I am buying the tank from has two 20 gal long tanks. One has the UTH already stuck to it and one doesnt. The one with the UTH is in a little better shape, but isnt worth paying an additional $20 for the condition alone. However, if I utilize both UTH's then the additional $20 is really only like $5 more for the tank as the UTH would cost atleast $15.
