I was wondering what everyone would think of about this item. I only have one cage, its a 20 gallon glass cage with a screen top, tin-foiled + duct taped in. There are two (almost) identical hides (soon to be replaced with better ones) and I am currently using newspaper for substrate. I'm currently using dial thermometers and humidity meteres but I plan on buying a digital thermomiter/humidity meter as soon as the next check comes in. I use one UTH as well as a Red-Bulb light. Would this item be able to support each of these, and would it turn them both on/off according to the tempatures? I looked for reviews and couldnt really find one.

Here are the 3 thermostats I was looking at. Would the first or second one be able to handle the two types of heaitng I'm use, or would I need the last one?

I will eventually be getting one thats a little more expensive, but I'm looking for one to hold me over. Thanks!
