What is the most reliable incubator in terms of temperature?

[InsaneBreeder]

My house has no way to regulate the internal temperature, and so the temperature can fluctuate anywhere from 60-85 degrees F throughout the course of the day. This is problematic with incubators that need a steady internal house temperature. What is the most temperature-constant incubator, regardless of cost?

I don't have a ton of experience but I do have two home made incubators. the one most stable in regard to temperature is one made of 3 inch thick Styrofoam. I am not at all claiming this will be good enough for a 25 degree temp swing though. I did have a thought though. you do not need to necessarily keep the temp of your whole house stable. you need to keep the space the incubator is in stable. Stable does not necessarily mean warm either. the space could be anything from the entire house, to just a room or even a box that the incubator sets in. a light bulb in a big box that holds the incubator could keep a stable enough temperature. Anyway just a direction of thinking that might help.
Other than that I have read comments on larger Sportsman type incubators that held temp even with outside temps dropping below freezing.

Thanks, that's very helpful

I would go with a cabinet style machine then cover the exterior with sheet styrofoam at least one inch thick leaving only openings for controls, indicator lights, and vents. My Dickey keeps pretty steady temperatures, but I'm not sure if it could handle that big a swing in temperature and I'll bet the GQF would not do any better. Added insulation would likely help a lot.
