I cycled my bator for 2-3 weeks before setting eggs, and the eggs have been in since the 31st. Woke up this morning to 94deg temps and a malfunctioning thermostat. I had another bator in the basement with a water bed thermostat running that I was going to use as a green house to start seeds for my garden. I took the eggs out of the bator, took out the hot water heater thermostat and replaced it with the water bed one. Now I'm sitting here babysitting the temps. they seem to be holding pretty good, I know not to make any drastic changes as it nears its sweet spot.
